I'm only level 12 but I have to say Rogue is really not that great. Shadowstrike is great for tagging mobs, but nothing really deals damage so far. Struggling with two mobs at the same time or >2 levels over me while the hunters are running around just blasting x.x
I've been swapping between a couple of different characters, so far Paladin feels really nice as DPS with the extra abilities. There's more to it than just afk melee leveling at least!
