I'm wanting to do an achievement run for Naxx 10man and want comments on what the minimum numbers/classes would be for a not-so-painful run.
Would 1 tank, 2 range dps, 1 melee and 1 healer be sufficient?
Assume that all chars would be around 350-370 ilvl

(Edit: I'm talking about ALL achievements. Not just boss kills)
