The last MMO I played was SWTOR and there you really had a structured quest line and a plot. While you also have a storyline in TESO I feel like you won't get to 50 with questing only. Currently I am level 20 but I only have Quests for level 21 (I'm playing Ebonheart) and this has happened before. Usually I balanced it out by PVP or Dungeons but I really find it a little annoying to always grind mobs/players for the missing 10-50% of the level (mainly due to the fact that it feels like MMO grinding. I'd love to grind mobs if it was actual Elder scrolls grinding). Of course I can also do the quests that are 1-4 levels above mine but I have the feeling that at a certain point it won't be 1-4 levels but 4-12 levels.
Are there some things that I can follow when it comes to finding hidden quests? I always find some quests when randomly walking past a wayshrine but even with those I don't manage to get a full level.
Also a thing I found was a certain Add-On which sort of functions like the old "Quest Helper" Add-On from WoW if anyone remembers that. The only thing with it is that it costs money and I really don't want to spend money on an Add-On (although it really looks great but 30$? geez...). The fact that there is a "Guide" to it somehow tells me that it is possible but I just don't get how It can be made (and no I don't wanna download the trial version of this thing since they want a whole lot of information just for the demo).
So is there something that I can hold on in game (If possible without addons) to reach lvl 50 without PVP/Grinding/Dungeons or am I basically forced to do these things?
