You should play it in deathmatch.
Then one person is called out at the beginning to be "it".  Then at the start of the round, everybody would hunt him/her.  Once a person kills him, then that person is "it".  You would have to manually count up the points for this game.  But I see it being scored like:(a) 1 point if you kill whoever is "it",(b) 1 point per 30secs of being it (or 1 point per kill while "it"),(c) -2 points if somebody who's not "it" kills somebody else who is not "it".
And you would have to play in normal mode so it would actually take a bit of effort to kill.

If you go by (b) the 1 point per kill while "it", you could use the games score counter minus the "not it" kills to get the final score.

Well since you'd need to educate people on how to play anyway it wouldn't be too complex for Deez' idea.
They'd need to have a mic or be in a chat room with you.

The deathmatch idea is easier 'cause you don't have to reconfigure the map to do it.
The thing about FC302's is that they'd all be after one guy and he can't really win.
What about the rest of his team? Are they allowed to take the points back. Once they get one point then it just turns back into an ordinary game of uprising. The thing is they wouldn't need to hunt down the captain, once all points are taken they only have to wait 'til time runs out to win. They could just camp the whole time on the points. Since it's the enemy captain they're after and he's the only one who can take points.

The thing about Deez' is that there's no real way of telling who's "it" other than letting people know via chat room or message. You can try and keep up but it'll probably be harder after a few switches. The other thing is there's no distinction in character. You can't see people's names (at least, not in hardcore mode)  so there will be a lot of random kills before the "it" get's switched.

I'm all for new mode ideas, if you want to reconfigure any of my maps, go right ahead. If this idea really catches o then I'll reconfigure them myself and publish an alternate version for the mode. I might even make some maps designed with this mode in mind.

Four winters? Man, unless there's some major lag going on it only takes me a couple seconds to shoot something in the chat room. (Keypad for teh win-sauce) Seriously, you've got a faster connection than I, you should have no problem.

Once again, Ubi is to blame for our lack of game mode options... Seriously, doom had more options than this, and that was like... The First Online FPS ever!!!  You'd think we'd have advanced more than this by now....
