WHM doesn't need the rework, AST does.
THANK YOU! This post sums up all I'm trying to tell people ever since AST came out! AST is such a stupidly lazy copy-paste job of WHM
AST is perfect and fun healer that can adapt to his co-healer. It's not a copy of WHM ... It's a WHM 2.0 or even 3.0, it's an evolution of your boring lackfull WHM.

If you want to rework something, rework WHM.
