Players that want to bully the below 50 campaign are already doing it. It has always been allowed. having access to better gear wouldn't change that.
wouldn't this get boring after awhile?
No, because it's a super easy way to earn a huge amount of stuff. You get stuff for winning, stuff for winning with style, and stuff for losing with style. No matter what, as long as you earn so much AP per match, you get stuff. That stuff and AP turns into gold. Amazing, really.
