Of course this is a joke, actually all classes can properly do PVE in PVE spec, so you can choose whatever you want
Sometimes when you cant do PVE with some class, maybe it's your fault (low gear, wrong rotation skill or build).
For we recomend some class, we will need more things like, how you want to play, healer, dps, tank, defensive support, offensive suport, cc .....
by the way, I tried the fullheal-psi, it's a too powerful class that the FBI invaded my room, while my mom keep asking what i have done
