arcane dps question

So i'm in the process of building up rep and just running regular dungeons to get into my 333's...

I have been running with guild, and have noticed as everyone is gearing up together, pretty evenly... that their dps is increasing and mine is staying around the same at 7k ish, given the fight. I'm currently up against a warrior and a shammy.. both are doing about 9 now.. it seems as i get gear my dps is increasing very minimally compared to the others..

I asked in trade chat about reforging and thru the trolls got some advice in reforging everything into mastery.. i did that, but dps went down a bit.. I'm keeping mana pool high, but w/ regular dungeons no fights are long enough to require an evocate ..

Any tips? should I gem a certain way (other than hit and i know i'm in greens) or is this just the arcane experience while gearing up...

Thanks!
Don't bother gemming or enchanting until you have at least 333s; I don't usually until I get 346.

Your hit is fine for heroics, your mastery is a bit low: grab a couple of the cheap justice point pieces if you absolutely cannot get a piece to drop.

If bosses are dying before you get to evocate, even in reg, then you're doing it wrong. Reg bosses (total group dps: 34k=9k+9k+7k+6k with wiggle room) should stay up for at least 40 seconds, barring boss mechanics like Rajh and Erudax.

7k dps is respectable, though, for an overall number in your gear. Hopefully that's not your spike dps.

I would suggest upgrading to a mh/oh combo instead of that staff. While it's a nice staff, the added stats of mh/oh can't be beat, especially considering the oh intellect enchant.

EDIT: Also, your average ilvl is now 329. You should be able to queue for heroics with a guild group, and they can carry you until your dps gets a bit higher.
