i like this idea because i am a person that cant play very often so it would make my progress larger.
really i dont know whats wrong with this so blast away at me and tell me its the worst idea ever and its been suggested before
Q: Then why is there a cap of 160 accrued BA?
A: Letting BA accrue (store up) when unused rather than being wasted means you don't have to be logged in to CB every waking hour of your day to be competitive. However, someone who doesn't play for a month (to give an extreme example) shouldn't get thousands of fights when he comes back; that's unfair to people who've been active that whole time. A cap of 160 is a nice balance between zero and unlimited accrual.
