Not upgrading Items slots I could understand, but character slots.... just see no real benefit to that. To each his own I guess, but I personally would not want to be bothered with some much unnecessary and non stop inventory management.

To some, item management is an interesting part of the game (some people even liked inventory management in Diablo, remember?). But personally, I agree.
Though, keep in mind that if you want to equip all your girls, you'll need at least as many jewelry slots as you have girls. And that is assuming you never merge dupes and only ever get single equipment slot girls from events.. With all equipment slots unlocked, you're going to need a jewelry storage the size of 4 times the amount of girls you have, and then 10 extra for upgrading..
