Why are you doing trist runs and tombs instead of just playing the game if it's their first time playing? I wish I could play the game again for the first time, definitely wouldn't want it ruined by doing trist runs / tombs if I didn't know why :S
On topic though:
Pally for conviction is great, you can put a point in rest in peace aura to suck up dead corpses and make your friend hate life / same with barb, bo is cool and you can always use find item to get dem epix for your friends / yourself
