I didn't see anything in the patch notes but has anything changed for fist weaving? I'm asking because I ran ToT LFR the other day, and was suddenly having problems with my mana when I didn't prior to the patch.
The only things I know changed were that I bought the VP gloves and shoulders, but my spirit's about the same - around 5750. Haste and crit are both about 20% unbuffed, only slightly higher than they were a week ago.
