Glyph of Blocking, Shield Slam bonus and Gag Order
I haven't been able to find the right answer for this lately. I was wondering if the shield slam damage bonus from T7 adds onto the gag order talent from the prot tree. In other words, is it a solid 20% increase to shield slam?
Also, with glyph of blocking, would that add another 10% damage increase? Or is one overwritten by the other?
The reason I ask is because my spec and glyph choice involves all of the above, and I was wondering if breaking my 2 set bonus from T7 would be hurting me at all since I have gag order and the glyph.
