Stone III Confirmed for WHM

[Ethos]

The only reason WHM is mandatory now is because two scholars can't stack their shields. AST ought to be fully stackable with SCH, rendering any combination of two of the three healer classes viable (hopefully).

If AST shields in barrier stance stack with SCH then WHM would need some ridiculously powerful new abilities to even be considered bringing to a raid. Ideally the whole reason AST has two healing stances is so that they can pair evenly with any other healer even another AST.
