New Rune Strike?

in
So, check out my build sometime, I have the extra 30 rune power mastry in frost. Anyone think that is a good idea?

Basically, with this talent set, I can buildup extra rune power and spam the freak out of RS. In a raid the other day, I was doing about 26k threat per second sustained over 35 seconds. In a heroic I was pulling threat off my army of the dead ghouls too with it. Anyone think its going to be nerfed? That extra 30RP is one extra RS when its fully loaded.
Thoughts? Comments?










Eh
I think realistically you should never be RP capped, I would much rather take increased spell hit, a few extra points for novelty abilites in Blood (shorter CDs, more RP gen) or even longer duration of diseases. And now with EVERYONE, tanks and dps alike, having to watch their AoE to not break CCs, I wouldn't even recommend taking increased range of most spells, especially AoE. You also don't have Aboms Might, a 2% increase to Str, pure threat/dps and 10% to party members Str, again pure dps.
