You guys have levers in use in ToC. Why not make use of them in a new PvP gametype.
Use the same A, B and C locations from domination so that teams cannot camp on a lever, and then activate a lever on a random spot at certain intervals (or random times).
Either gives individual/team buff or individual/team neg effect.
Could make TDM more interesting and turn the tides a bit if you get a good buff.
