bscIf the coach req is 1 season in open then I doubt they understand how to push or at least be able to teach it
Off classing in general shouldn't be permitted
We discourage off classing en masse, but the coaches can control that. Also, most people I've met who have played one season and want to coach are people who have been getting mentored, do demo review, and play a lot of TF2 so they are pretty qualified to coach people who are *brand* new to 6s. It's not too complicated to teach people how to rollout or comm.
Pushing into heavy+pyro is difficult IMO, but it's not like they aren't going to see that in any league they play in, so I don't see the problem with using it in a newbie mix.
