I keep thinking of Battlefield 2 maps when I think of this kind of gamemode LOL. I like it because I think it may actually slow down some of the gameplay for a change as a tactic. Instead of never worrying about death, it should be counted as a penalty.
It also leads me to think of a king of the hill with 2 or 3 different hot spots with this kind of action. OK, im done speculating, but good idea tho.
