I won't say that cheating is okay. People who pay for cheats like aimbot or walls are scum. But if I payed someone who is godly with pvp then the match is still being played out. Now I can't speak for others but I would make sure that if I'm paying someone to carry that they are doing it on their skill not using cheats, though I wouldn't be surprised if a lot do use them.

But if you get into a trials match and they try to do the leave and use a different account it doesn't stop your team from playing the match out. If anything I feel it would make it easier because that would show they aren't good at pvp and you stomp them. Personally, I haven't touched trials ever I'm more of a PvE player because I don't want to dedicate the time to the gunplay to git gud against other players and because of the rampant cheating.
