My char: Rhalox - Stormreaver. I havent posted enough, so not yet allowed to give the link :S

Been having a heavy drop in my dps compeared to my other guidlies.

Heard allot about haste beeing the new mastery. Is it time for me to reforge / gem to haste?
Then EM - PE as talents.

Also I have gotten the thunderforged rentaki, should i change that out with one of my other trinkets? When i used it it puts me about 2 / 3% over the experise cap. I know hit is good for me for more white hits, but to my knowldge expertise doesnt do the same??
