Related: Are we allowed to change hats on medic to keep your uber while forward/back spawning? (usually happens that you get trapped in your 2nd spawn & use it to get quickly to your last retaining your uber %)

Yeah but most meds play med because we can't aim for shit..

It's always been allowed as far as I'm aware, provided you adhere by the class limits in terms of the people you have alive. You can switch everybody to demo if you want, as long as you have only 1 demo alive at any given moment.

[...] I discussed this with admins 2-3 years ago and the conclusion back then was that it wasn't allowed. However, the rules are more ambiguous now than back then, and since there's no definition of what classlimits actually imply, I suppose the current rules would allow it. I just see some problems with this; for example a "demo down!" call might lead to a rushed push for the final point, and allowing scouts to go demo in such a situation might turn the tides entirely of such a push.

[...] There have been several threads like this before, and the admin response was always 'is allowed'.

As I understand it. As long as you don't actively affect the game in the way you break the rules, if you don't leave spawn or just leave then realise and run back in, there should be no problem. As long as no more than 1 medic 1 demo 1 heavy and 2 of each other class are active at any given time in the game, no rules are brokded

I'd say no. Due to how the game works, you remain the class you died as until you respawn, regardless of class switching. This means you technically have 2 medics "active" until the dead medic respawns, which would be exceeding the class limit.
