Started a new Shaman yesterday, just dinged lvl20.
While I am interested in seeing the story via questing, I also kinda want to lvl up fast so I can get into Legion content asap. Right now, dungeon is a lot faster, to the point I gained 3 lvl just from a single Wailing Cavern run.
Is there a lvl where I should stop Dungeon Spam and just stick to questing? If so, around where?
