Would WHM be too strong with some support utility?

[Rawrz]

I've been saying it for a while...
Give Stoneskin an in-battle proc, off of whatever ability(an overcure proc, Crit cure whatever, random Stoneskin) that gives an in-combat Stoneskin 2 use. It would easy to develop for SE and it would be great to have in game. Easy fix for everyone.

I was thinking a more useful version of old benefic.

Change the Stoneskin passive to something like "One with Earth"
Casting Stone, Stone II, or Stone III have a 15% chance to reduce the cast time to instant and the MP cost to 0.

To "pure" healers, this would be an unnecessary buff. To DPS aggressive WHM, this could be a game changer I feel.
