Hello guys, I'm looking for some advice about from my talents to my geming, usually on multiple targets my dps could get up to 4.5, and on single targets it doesnt even reach 3k, recently i entered to a ICC 10 man with the guild and I reached 5.6k Dps at the start, however during proggress it fell all the way to 2.9k Dps, so my question is, what should I change? my geming? my talents? I really want to improve since I'm wanting to get on raid every week, and not be left behind for my low dps.

This is my char

So any feed back will be very welcome
