The "Briefing" Screen.

Before you enter the game, along with weapon select, team select, etc, there could be a option to choose where you spawn. This'll help people avoid spawn campers and get to a better place to defend in assualt. For the noob class and guests, there could be a Question Mark somewhere on the screen, which they'd use to find out how to spawn. It could also link to other guides.

Disadvantages:
Noobs could be in-game and looking at guides, and take up space for others to play
Guests probably wouldn't know what to do, and not play Pawn
Spawn Campers would have a hard time covering all the Spawn points, therefore hating this suggestion and me
Might cause more lag.

Possible Answers:
Auto-Kick, if inactive for 2 minutes or more, then you are kicked from game.
Guests don't have the option to choose spawn points.

that's the decision the map makers make. You never choose where you spawn in other games.

[KiteRider]

No, from the ones there already are. You choose which Spawn Point, not a place on the map.

I like this idea it will add a broader element of tactics to the game as you will have to cover ALL spawn points not just one this will work best on maps where the spawns are not on the same screen(battlefront,arena)
