The available maps don't help, either. Whaleship is mainly mono-type, Clean Sweep is skill activation > all, and everything else can be rolled by whatever.

Agreed, personally I'm finding that skill activation is still King of the ability types with added weaknesses being the next strongest. If crit was an additional multiplier after weaknesses then I could see it being really strong but until then it's a rare nice to see but skills do more number.
