Idea for when the level cap increases

We all know it'll happen eventually. I think many of us were surprised it didn't happen with Territory Battles.

I think that if levels that are 85+ stop requiring credits, but instead require insane amounts of training droids, that would be really cool. It would mean that getting past the current level cap won't put (even more) strain on your credits, and it would be a way to make training droids relevant again (because they surely aren't now). Obviously an additional tier of Droid Heist would be good with this.
