Best Trio That Doesn't Use Enchanter

[Vexenu]

Yeah, I'm a big advocate for Paladins, but the Monk is clearly better with Shm/Nec. You can talk about throwing a Paladin in a non-Enchanter trio if you also throw in a Bard for mana regen (hence my earlier suggestion of PAL/BRD/DRU). But at that point you really can't call it a power trio, just one with fairly good synergy with a lot of room to play around and experiment.
