High TTK games with high uptime worth maining besides Overwatch?

see title; genuinely just looking for anything to play long-term for the joy of improvement and not much else

i find tacfps uninteresting unless it's with friends and BRs are just boring because of the relatively small percentage of time actually spent in fights per match

i play overwatch currently and one-trick soldier 76 for my kick but the game has just been on a downwards trend lately and i'm kind of over how boring it is to play a game run by devs who really should be working on hearthstone instead
