I do not personally agree with this, but i have some ideas for the re-spawn timer.
Make it that Medics can deny peoples rev request and make re-spawn timer go straight to 30 seconds, instead of waiting 3:30 all up (extra 1:30 when you click request)
Possibly make the re-spawn timer 1 minute. And if someone request medic it extends for another minute
Make Medics that are Senior Paramedic + only aloud to accept/deny request's so Pubslot/trolls just dont accept and not go to the rev.
Or add all 3 in the above.
As for Combat-logs, the only solution I have is to make it when someone combat-logs they get sent to prison for 10 minutes.
Just an idea end of the day, Open for more feedback
