Right now I'm at almost 12%. Mastery is on the back burner for me as I don't think my Crit rating is high enough to support it, just yet. I'm at 20%.
I'm kind of amazed because in most fights it used to be number 1 but now it's doing close to 30% of my damage at times. With increased damage (taken) mechanics only Execute can get close.
Thanks in advance,
