Notice in other threads that ppl advice to maybe spec the whole group as dps since most mobs are dying fast:

so it would look like : one combat rogue (main), one boomkin druid, one ele shammy

imo:

pros : 3 dps, only one melee to manage, 2 rez, can heal if things are goind bad.

cons: no tank (dont think it hurt for questing), maybe hard to set up keys for 1st multi boxing.
