Thanks a lot for the quick answer!
Everything noted.
One more quick question: Somebody from my guild argued that 21 expertise was better on the ulduar patch (Which means you may get parried/dodged your auto hits, but not abilities) than 26. Thoughts?
I currently have 27 expertise, without any gem or enchant into it anyway, so it doesn't matter much unless I find an item with less expertise and more other stats!
