Blizzard allows Characters copy from one of your account (EU, US etc.) to the PTR in order to test the latest patch but is it possible the other way arround. My biggest concern is : if I loot an incredibly good item (or something I've been looking for month on the "real" server) in the PTR, will I be able to transfer it back on my main account ?
Blizzard state in their forums:
As a reminder: Any progress made on the PTR will not transfer over to your live account.
It is impossible for a couple reasons:
- Balance: the drop rates might be different on PTR than on your normal account.
- compatibility: the items that drop on the PTR might not even exist on the "normal" system, it might have a new affix. Or it might have an affix that can't happen in the old version yet.
No.The test realms are for testing,items can change etc. :)
None of the progress made on the PTR will transfer back to the live game, so any items, experience, or achievements you earn while on the PTR will not advance your characters on the live servers. It's a great place to test out the new changes and features from the patch, though. I definitely recommend hopping over there to try it out if you're interested in any of the new stuff.
