Ok so obviously this character is too strong but I think it will end up being a positive due to the fact that it will bring more nubs into the game.
Warlock gives nubs the opportunity to drop in the game and become godly without much effort. This move will bring in a bigger player base and will be an overall win for the game.
I think Blizzard nailed this expansion.
good point, once they think the game is too easy, they'll try for a "harder" build.. hopefully wanting to pvp and see what the other chars can do. i havent dueled yet in this new expansion so idk how the warlocks truly do against other tried-and-true builds
