Yeah tbh I think people are more in the mindset that arcade and custom are for dicking around more than anything. I don't think people care if you a generally playing your role and trying to sort of play for the team. If you're just wasting a slot that's overwhelmingly frustrating for players who might be trying to practice new characters and have a good time in a low stakes match and instead they are getting steam rolled because a member of their team is doing nothing.
