Arcane raid questionFollow

I am kind of new to the whole raiding thing......I have been using an Arc build for everything I have done so far and have really been enjoying it (Missile Procs with Arcane Power, Trinket, and Sundial of the Exiled are fun :) lol) and have noticed that I really never use Arcane barrage at all since I read that it is better to use AM regardless if it procs Missile Barrage or not with the ABx3 rotation....So I ask to I need AB for raids or even heroics on that part??? I honestly never use it....Maybe as a finisher on trash occasionally, but that's about it....Or is the utility of that instant spell more important than putting a point somewhere else like maybe some Student of the Mind.....I currently use the spec in the TGMPE, the 57/3/11 one (except I put 2 points in Student of the Mind instead of Magic Absorbtion for more crit and regen)...Tell me what u think

Personally, the only benefit I see in deep arcane is the tons of mana and spell damage. If you want to top the dps charts in raids, you should look into deep fire. The benefit of raids is that you sit frequently so you dont have to be as mana conscious as you would be if you were soloing.
