Something that has been bugging me for a while now as a 2H Frost player, is how much difference it makes having Rune of the Fallen Crusader proc vs not during PoF. It is another one of those procs i need to rely on in order to do decent damage.
However if it was removed, and the class rebalanced around not having it, would open up a lot of new ways to use Runeforging.
Suddenly i can use Rune of Razorice as a 2H frost, and then it opens up a lot of new talent combinations. Or UH could use Rune of Hysteria for that extra RP generation etc.
