Bring it back, but give it a different name. Something like... Deathtrap. So called, in lore terms, because the Defenders have "lost" their MCC, and has led the Attackers to the last stronghold, and are using it to kill the enemy.

I saw once someone suggesting using all the Game Modes for one FW battle. Ambush will be when the Attackers are trying to gain a foothold, OMS is when they have a foothold and can call down installations, Skirmish is when the foothold is strong enough to be able to hack installations, and Domination is when the Defenders are nearly defeated. Add this mode, when this is implemented (please, CCP, it would be great), and put it after the Domination, and it will be when the Defender's MCC is destroyed, the Attackers are trying to capture the District, and have to dock the MCC there, to let some drones into the base to wipe out resistance.
