[Phantasm]

My go to foursome:

Monk - pulls/dps/tank (iksar of course)
Shaman - dps/slows/buffs/side heals/everything? (iksar, naturally)
Cleric - enough said, cleric gone cleric (can't be be an iksar, womp)
Enchanter - insane dps/cc/dps/dps/buffs/dps (can turn into a half iksar, acceptable)

this foursome allows you to take on almost any camp in the game, pull any camp safely, engage almost any mob with minimal "oh shit" moments

the enchanter/shaman combo allows for some redundancy for any inevitable misfortunes, cleric can provide resses and monks are all around badasses. The only downside is that not all of these classes can be iksar
