The -2XC looks really weird, until you realize it's going all in on the Remote Sensor game. Between the Bloodhound, C3i, Command Console, and the free ton of Comm Gear all mechs get, the Warlord can monitor the feeds of twelve remote sensors at the same time, regardless of wether said Remotes came from itself or laid by someone else. That can be a huge advantage in double-blind games, or large campaigns where you want to keep an eye on huge tracts of land(actual land) even when you don't have any patrols in the area.
