It is a typical end game problem developers in all sorts of games fail to address. Its a huge grind at first, but when it hits critical mass there is nothing the player can do anymore.
At least the fish allows you to spend your earned stars, once you don't want to play Infinity Mode anymore. But even that becomes pointless after you have reached max rank.
And it is extremely difficult to come up with a solution for that. Which also rises the question how useful a level system is in the first place.
And i don't care about mastered characters so far. I work on unlocking all the skills i want and will focus on Master rank later.
Is just as you said. I mastered them all so what else to do next? I stop playing the game afterwards.
