Ok so first im still gearing my pally nearly at 33k unbuffed about to craft the saronite swordbreakers and the boots from ulduar but the thing is all of this gear has a shit load of expertise right now im at 32 expertise wihtout that glyph.
My talents i know drop SA down to 1/2 and put the last point in 3/3 crusade.
but the thing is how much difference would that 10 exp make going from 32-42 while tanking most of the time, for offtanking i dont want to use the glyph but sometimes i get asked to MT and i think its worth it
