If you want to quit just because a balance patch doesn't go your way

Just quit and move on.

Every balance patches will come down to;

Owner of buffed monster: Happy

Owner of monster not on the list: Angry

Personally, I don't think this patch is as bad as people made it to be. I know many people aren't happy because their monsters didn't get a buff, but they will eventually. But if you want to quit just because a balance patch, then feel free to do so.
