Dream Group

[ride the spiral]

Paladin: snap aggro, pre-mez break aggro, LoH
Cleric: BiS Heals, HP buffs
Enchanter: BiS CC, Clarity, Haste, Slows, Charms
Bard: BiS Dungeon puller, CC, Charms, HP/Mana Regen, Snare, Melee Buffs
Rogue: Sustained DPS, lock picking, corpse retrieval
Wizard: On demand damage, BiS roots, Evac

SK is up there with Paladin but I just think Paladin is the BiS dungeon tank because of downtime heals, caster interrupts, and breaking mez safely. I also think Wizards are slept on a little bit, If you get a seriously nasty pull, you have that on demand damage to blow stuff up instantly. Plus Evac is great utility.

This is my perfect group. It may not have the highest DPS output (I can agree that 4 enchanters charming is best there), but I think this is the most balanced setup. Over a long period of time, I believe this group would be the most successful.
