Question, and the realization I have nothing to work for in this game anymore

First, my question is; what if Arcsys increased floors? to like 20? or 100? would that fix any problem with the pool of mixed skill that is floor 10 and celestial? like i feel like there isnt enough floors or ranks to actually gauge my skill because anyone in floor ten can be really really bad or God himself and you never really know what you're gonna get

also i just realized that I dont really have anything else to work for in this game. Ive hit celestial 4 times so that milestone is done and dealt with? so like...what else is there? sure I can play this game for fun but i still would like to feel accomplished.

Im really thinking about moving back to GB or SF6 for the time being iunno
