Shaman (Skills List / Talent + Glyph Calc.)
Unleashed Rage in 3.1
in 3.1 this is getting changed is a 3pt talent, along with the 4%/7%/10% AP bonus on crit it will grant 1%/2%/3% more AGI. What I would suggest is changing the agi bonus to expertise, the lack of mail gear with expertise is very hard to overcome.
I believe this change (Agility -> Expertise) was actually made today. No promises until you actually see it on the PTR. (Source)
