PvP skill... icky, mostly not applicable to PvE, so i never spec in it. Too much mana, not enough damage to make up for it unless it crits, and if your an affliction raider, you are not supposed to be stacking crit... max damage and a little bit of hit should be your focus. But again, this build if mostly for the 25 mans, like Mags, Gruuls, etc.
