Blizzard has released the Diablo 3 downloaders. They allow you to pre-load the full setup (around 7 GB) on your PC without asking any credentials. Of course without a valid key these files are completely unusable, they will only work when Blizzard decides to make the game playable on servers through Battle.Net login authentication.
To prevent the download from pausing while you're playing WoW, do the following in the Blizzard App
Click the Blizzard icon near the upper-left corner.
Click Game Install/Update on the left side.
Uncheck "Pause updates when I launch a game." You may need to scroll down to see this option.
Click the Done button in the lower-right.
Along with the two forums you linked, this Battle Net forum discussed this as well. While it doesn't contain any information directly from Blizzard on this, a user gathered that this is more than likely due to a connection blip from the server.
From what I've gathered there is only one very small window that the Hearthstone client sends the opponent ...
It's not implemented yet, apparently Blizzard has plans to implement it "soon", which is likely to be sometime between now and the end of times (i.e Soon ™). Especially since this post is already over three years old.
I"ve also been wishing for this simple functionality for years...
The option to appear invisible was anounced back in 2012 but was missing from Battle.net for a long time and a 2014 tweet mentioned that it wouldn't be included for some time.
New Update: It's Here:
As of October 2017 the option to appear offline is implemented in the beta version of the Blizzard Battle.net app and will come to the standard version later. (...
It is Blizzard's position that the session ID hijacking claim is bogus. Bashiok stated in his post that thus far none of the compromised accounts they have investigated had an authenticator attached prior to the compromise. A further update specifically asserts that the session hijacking being described is technically impossible.
The advice to use an ...
A Diablo 3 License is Non-resellable. Once the key is activated it is tied to the owner's Battle.Net account, which is non-transferrable and cannot be sold under any circumstances at this time, per the term of Blizzard's EULA.
So NO, your friend cannot sell you his copy of Diablo III in any legal way.
Update: Some in game items are unavailable for gifting.
It is currently possible to gift: World of Warcraft, WoW mounts/pets, StarCraft 1/2, Warcraft 3+expansion, Diablo 2+expansion and Diablo 3+expansion.
Pre-purchase of Overwatch and WoW:Legion seems to not be giftable.
From the blizzard support page:
Heroes of the Storm in-game ...
You can use WinAuth, which is a popular third party authenticator for Blizzard games. It's not quite as secure as the official means since if someone gains access to your computer they can use the authenticator, but it's far better than nothing(you could probably put it on a flash drive so it isn't always on your computer).
Season Lock fixes your League. You can not be promoted or demoted, but you still earn points within your Division. Bonus pool also stops accumulating for all players.
Your hidden matchmaking rating (MMR) is still adjusting unrestrained, though. If your MMR stabilizes within another League during Season Lock, you will be promoted/demoted immediately after ...
From the Diablo Wiki:
What does the gem in chat do?
Nothing, other than change colours and put up the occasional unusual
message. As was explained to us by a Blizzard employee, it was not set
up to send data to the server, and that would be necessary in order
for it to have any other function than to just "look good."
If you get desynched/...
Blizzard used to offer a J2ME-based authenticator for older phones, but they have since discontinued it. They now offer authenticators for iOS, Android, Blackberry and Windows Phone 7.
Other than a phone, your options would therefore be a tablet, iPod (touch), or the physical authenticator.
For those without such a device, the other answers propose ...
It's a random number that is attached to every BattleTag, no matter whether the actual name is unique or not (the number makes it unique as the combination has to be unique). It's usually hidden though.
It essentially makes your name unique while allowing the readable/name part to be used multiple times. That means, you don't say a friend to add "BattleTag" ...
So, with respect to this specific exploit, the most important thing is to stay out of public games, and under no circumstances accept an invitation or join request from somebody who you don't know.
You'll also want to disable Quick Join, and verify that your friends are who they say they are before playing with them as well. Once an account is compromised, ...
You don't, unfortunately.
The Battle.net desktop application does not have any support for what Blizzard refer to as "legacy games". This means that Diablo 2 and the Lord of Destruction expansion (amongst many others) are not available for installation or management through the Battle.net desktop application and can only be installed by logging into Battle....
The recently released Battle.net Desktop App now includes the ability to chat with your friends if they are logged on to that same app, or any of WoW, SCII, D3, Hearthstone, Heroes of the Storm or Overwatch.
If you know the exact battletag you can visit the official site: http://battle.net/d3/
There you will find a nice diablo oriented display of all the important and more or less unimportant stats including but not limited to: Equipment, followers, playtime and enemies killed.
However if you don't know the exact battletag you can visit the semi official site ...
Blizzard released an official statement about the current situation. Their official statement denies that there are any current exploits, or that Authenticator-locked accounts have been compromised. (We can always trust what a company says about their own security, right?)
However, it also mentions that, if you're concerned about security, in addition to ...
A stalemate is detected when no one does the following for 6 minutes (3 mins for a warning, then 3 mins for the stalemate).
Produce a unit
Construct a building
Research an upgrade
Destroy an enemy building
It sounds like all of these condition were met above, so I would say it is not a "bug."
As for the Zerg buildings dying, I ...
Do you have a smart phone? Blizzard has an authentication app that lets you "validate" who you are.
It sounds like there is ghosting software as soon as you log off, but you have access to "install" applications when you are using it. You mention that you're downloading it every time. Why don't you copy the Starcraft 2 folder to a USB stick and then just ...
Warcraft 3 had:
Clan Support, which meant that you could actually put your account in a clan and have it assigned certain ranks. It also included a custom chat room for your clan, where the clan leader had a shiny golden icon (Oh how I loved it) and could ban people from his village.
Automated tournaments. Basically every other day, there was a completely ...
Be careful, it might be spam, I get several "your account has been hacked" emails each week. purportedly from Blizzard, but they are not.
In this case, it does look like you have actually been hacked (possibly because you went to that link?)
In that case, you will need to contact Blizzard account support.
You can unlock your account if it's locked, or ...
For Master, Diamond, Platinum, Gold, Silver, and Bronze leagues, you will not be demoted for inactivity. (Inactive players are demoted out of Grandmaster league.)
However, your league membership only lasts for a season. And, if you are inactive for a full season, then play in a later season, you are considered a "new player" for league purposes.
Edit: If ...
Accepting a friend request will allow that player to see when you are online, see what game you are playing (and limited information about what you're doing in that game) and send you battlenet messages. This will also enable certain interactions in some games, such as challenging them in Hearthstone.
You can remove a friend at any time.
While the answer given by Wondercricket was true when posted, there's actually another reason why this is happening more frequently now. In October 2017 Blizzard added "Appear Offline" mode for players - partly to counter queue sniping.
When you choose to appear offline, opponents will now only see "Your Opponent" as their opponent's name.
StarCraft was written in a time before Unicode support became commonplace. As a result, it relies on the computer to work in the correct codepage - and as the Mojibake shows, your computer isn't.
What you can do is either to change your OS regional settings to use an appropriate language for non-Unicode applications (requires a reboot), or you can try to ...
The closest you can come to this is to download a diablo 2 character editor and adding an item into your inventory (if its a ladder only item such as a rune word or a unique charm, you can just create a similar item with the same stats as the rune word).
