Maybe instead of nerfing these upgrades you could just buff every other upgrade. Stuff like decreasing their cost (Party Time & legendary upgrades) to increasing their effectiveness is always welcome as a no-life max rank. Though it may be unfair to those just starting in the game with less options.
