i am thinking of running a group like this:

tank: pally (aura, blessing, seal)
dps1: ele (hero, sp, crit, haste, other totems on top)
dps2: moonkin (mdw, hit debuff, spell crit, spell dmg %)
dps3: wl (crit debuff, replenishment, +hp or int through the pet, soulstone, healthstone)
heal: not sure

priest? provides sta buff and could be used as dd with only minimal equipment changes required
pally? more blessings, auras, seals - only downside: can not become a range dd
druid & shami - no additional buffs

what do you guys think?
