Venos and archers. Can't choose between em. I love venos for how tanky they can get and that they really good, archers cause I love the rage and dmg they can do and their aps :3
I had a archer too, R8. They're okay when they are channeling.But i never had a Veno, people tell me that they're good too!
My current favourite class is Mystic, it changes often though.
