It might be nice to have a way to quick switch between ability loadouts or have an additional row. I ended up with more abilities than slots, although I did figure out there is a way to swap them out. 

I think the way that it is currently is by design? So as to stop the player from simply having two rows of charging abilities (As opposed to the generally weaker passive abilities) thus winning every fight with a landslide victory while charging up the next. but the load outs is a cool idea.
