I seem to be plagued with hit and crit (affliction) on all my item upgrades. Lately I've noticed that I've been getting lower IL items with much better (mastery and haste) itemisation. On the one hand, I'm looking at IL and thinking that even though it's not perfect stat allocation, it's still got more stat allocation, and yet on the other I can't help but feel that I'd be better off with the lower IL gear.
Short of doing a lot of math and SC experimentation myself, I was wondering what people's opinions and experiences were on this matter.
