I turned on auto-decimate and it seems to be triggering even before I've unlocked crushing margin.
The super secret gun is cool, but takes too long to charge up.
Perception got the short end of the stick; none of the forms are based around it and there are no abilities that use it.
EDIT: Seriously what does the last form even DO? I'm having more trouble beating the final boss with it than any other form. You couldn't even give it an ability that makes AM increase your stats?
