Healers need an overhaul

[Silver-Strider]

Pretty sure Stoneskin II, the AoE Stoneskin, could only be used outside of combat...

But yes, it was spammable, and on a tank it was pretty decent absorption if cast by a WHM (then worth 18% of target HP, up from 10%).

Stoneskin 2 wasn't usable in combat but Stoneskin 1 could still be applied in combat and was required for certain mechanics, like Prey in T10 of Coils and was useful to help mitigate Teraflare in T13 because it could stack with Addlo/Succor.
