I can safely say, that if its me your up against, it will not be a BG that has bouncers/Fists/Scarlets et al. If you quit, you'll be doing yourself out of an easy win.
Even if Bouncer and Fist get nerfed, then you'll start running into Master Axeman again. Also, depending on how much expensive champs i have, I would probably still run Bouncer.
