So im just starting my multibox journey and had a few questions before i really commit to a certain setup.

I want to be viable in 5 mans possibly raids (prob have to solo for raids, not a major problem)

I like the idea of still being a beast in world pvp (or is pve better for less headache...opinions needed)

Class combo:
The main questions are if im going with 3x is it better to just focus on 3 dps. And if so what 3? Mages/locks come to mind.

Or would the trinity be better healer/dps/tank?

Other 2 considered combos are 2dps/tank. Or more likely 2dps/healer.

A lot of this is subjective but i like opinions and personal experiences to help guide my choice.

Been having a blast trying out different combos up to 8-9 but iam at a point where i want to commit to something and be viable endgame.

Also opinions on profession combinations is appreciated.

Thank You.
