I think I said pretty much what I needed to in your other infraction, I just wanted to give you some more time off.
I ve tried many variants of stats and items in enh sim due i have plenty of them and i can say that that it gave me nothing. I have good results on most of bosses using haste and critbased items in Ulduar but iam still far 100-300 dps from Wowmeteronline Europe top 20 on Kologarn and Iron council, for example. Only explanation that i have is difference in raid tactics. Can someone here help me to optimize my dps on this encounters and sorry for my eng if there any mistakes not my native lang.
