Blocking AFKers for good?

Well I was watching the MLG gameplay last night, and the player I was watching “pressed X to spawn.” what if you HAD to press X in order to get back into the game? This could effectively block all AFKers for good.

If a team was winning by a short amount (lets say two kills) and there was a short time left, the winning team could die, not respawn and win the game that way, therefore screwing the other team out of a possible victory.

Good idea on paper, badly executed.

Then I would just not hit X with the rest of my team, and not even bother playing. Just waiting the clock out. HLG Evolved.

Too easily exploited. Get in the lead, die, refuse to respawn. Just wait out the timer and collect your credits for winning.
