Before everyone says "Dice don't look at these forums, tool" I will state I'm just puting this idea out here. In 2142's Titan mode once you blew up the enemy titan it wouldn't just explode right away but in peices. Players would have to fight off enemies while running to the back of the ship and jumping off. This was probably the most epic parts of the game and I think it would work nicely in Battlfield 3. Maybe in rush their could be a larger building with objectives in it and once you blow them up you would have to race out before it crumbled on top of you.
