What makes WHM special? Nothing anymore.

[winsock]

WHM has, on average, 6 instant (single-target) heals available over 5 minutes and AST has 7 if used on CD, so "availability" of oGCD heals is still nearly identical. If you want to include Assize (a tool that AST has no equal to), WHM has 9 instant heals available and AST still only has 7 over 5 minutes. At 8 minutes, WHM has 13 available while AST has 12, and at 10 minutes WHM has 18 and AST has 15. So your argument that AST has more instant-heals available than WHM is also incorrect.
