@Cleftobismal - Maybe this might be a better way to visualize this (objective values used)

WHM Healing = Grade A
WHM Utility = Grade D
WHM MP Restore = Grade B

AST Healing = Grade A-
AST Utility = Grade B+
AST MP Restore = Grade A+

Healing requirement for A12S is A-

With that in mind, do you think players would want WHM or AST more? While yes, people should play what they want, when you objectively compare the kits in that fashion it's hard to argue that you wouldn't want to take an AST over a WHM if you have the option to do so.
