I'm not a jailbreak player but I play deathrun which has bhop. Bhop can be really op depending on what the speed limit of said bhop is. On deathrun, it's set at 800 while the normal walking speed of every class is set at 300, if i remember right. So in my opinion, if you set the speed cap to like 400-500 then it wouldn't really be a problem. Saying this again, I don't play jailbreak so I don't know what speed cap would break it, but I think a tight speed cap should be considered when adding such a feature. Also, Can't scouts double jump on jailbreak? I think that would break bhop for them.
