I like the idea of having awards for useless stuff like winning streaks and such, its just another motivator to do something useless and try to do it better next time.
Instead of removing it its better to fix it (Like safe screens, you can leave game without losing winning streak if you leave when not in match)

Also I dont think its gonna fix much (at least for me), I dont need this trick to go 50+ winning streak, so the only solution is actually adding more stuff you can spend you cash on.

edit:
I dont know is it me or what but sometimes I fire up minibash and it feels just different, since there is no patch or anything I am just curious is anyone else feel like physics changed or something.
