Best Trio That Doesn't Use Enchanter

[Vexenu]

Very hard to make a case against NEC/SHM/MNK for best/most powerful, but I think Paladin/Bard/Druid would be fun, strong and versatile. Tons of mobility, easy pulls with lull/harmony, stacking damage shields, outrageous amounts of healing/regen. DPS is a little low, but you'd manage, especially if you prioritize Druid and Bard charms when possible.
