Personally, I have seen flyroes being used the right way and don't have a problem with keeping them. I've even punished a few that have exploited maps. If people are too stupid to try and cap the point (or call a mod on when there is a problem) then they shouldn't even play TF2. It really isn't that hard.
And guess what guys, we have plenty of mods and admins for the TF2 division. I bet...no, I GUARANTEE, there will be one on that can help you. If the rare chance comes that they can't help you, then post a ban request.
Just because two people don't like something and are too ignorant to use the solutions given to them, doesn't mean we should remove it. That is my input.
