It doesnt work at all for me.
Works properly if i cast it on myself, but if i cast it on the MT it *never* procs the 50% crit on me (while it should be a 100%proc...).
The tooltip says "Each time the target takes damage they gain a Sacred Shield, absorbing 500 damage and increasing the paladin's chance to critically hit with Flash of Light by 50%."
so i assume i can cast it on the MT, when he get hit the SS absorbe the damage and give ME the crit buff for the FoL but seems more like that additional buff goes on the SS target.
Even a GM assisted a whole fight in naxx and while he confermed what i said above, he saw i never had the +crit effect on me -_-
Anyone else with the same problem? Am i missing something?
