Topic of the thread:

-WHMs got QoL change that gives them AoE Stoneskin w/ Graniteskin trait (QoL = Convinient)
-SCH requests a similar QoL change to all cross class Stoneskin for similar convenience (while maintaining the normal 10% of max HP shield)

This QoL change for WHM in no way shape or form impedes on a SCH's ability to heal.
Likewise, a QoL change for SCH to have AoE Stoneskin cross classed in no way shape or form impedes on a WHMs ability to heal

Is this QoL game breaking in general? No.
Would it be nice to have. Yes.

Aside from it being a programming issue potentially, why NOT allow it?

All I really see is people feeling their now SUPER SPECIAL that they have an AoE Stoneskin and don't want to share a QoL adjustment with their healing bretheren even though it wouldn't make or break anything in the game.

@.@ Like... seriously?!
