Before we debate ob this, is that even possible? @kbraszzz @Rejects @Ohstopyou :(
EDIT: As far as I understood demos were restricted in order to prevent mass freekilling.
We have enough staff already, jailbreak is pretty much always maintained.
And if people want to mass freekill, they can just go heavy.
Perhaps just unrestrict demoman, the sticky jumper can still be banned, and add rules about sticky trapping. If you're a soldier, you can play with a launcher if you're willing to accept the risk that you still get punished if you freekill even accidently. Same should apply for demo.
