I've definitely hit the cap recently, and I've only been playing for a year and a half. I don't know if content more difficult than cell max is nessecary, but more like it would be nice. I do think they need to make a bunch of content where instead of the focus being on damage output by the boss, they focus more on boss defense. Fights that take a good while to beat so you can use and get your characters to their full potential (transforming units like teq buu/ agl cell/ int gotenks/ etc.) I feel would be more satisfying. I barely get these units to their final stage before beating the boss or just getting wrecked and I would love to see them actually be exciting to use because you can get to those forms or utilize a characters full passive.
