..you'd see a hell of a lot more flaming if normal chat was allowed..

This is why it is proposed during the 60s warmup, where you don't fight yet, but solely prepare. The chat mute would still persist during the match, where you are supposed to fight after all. So your scenario wouldn't have happened.
Be wary though that people can report you for harassment or griefing, just like outside PvP. It's not worth to lose an account because of it.

I know, but it's really hard when your team is just...stupid. Especially when you're the healer, at which point there's literally nothing you can do about it except either let somebody die so you can help kill something, or in the case of being unable to heal through the damage, just letting the loss happen.
