Would WHM be too strong with some support utility?

[Lastelli]

the problem with the WHM is not the WHM.

the problem is the AST got buffed too much.

If they gave back proshell to whm then it would be once again mandatory in end game content, so no way. I agree however that graniteskin should be back as it was in 2.x.
Anyway, whm still has way more healing power than ast, imho healers are pretty balanced right now.
