Who wants to bet the blue flame AA will unlock once you hit the inheritor rank as well as the haunted helmet. Unlike the haunted helmet that will cost 1 cr it will cost upwards of 20,000,000 cr so all the people who reach it and have already spent most of their credits will be screwed!?

By that point you'll have 20,000,000+cR by far. The new armor options stop around general. So any cost that Inheritor will have won't even matter by that point.
