The Falchion is outdated and does not fit into the current game's economy or meta
With the changes to components, tanks will not be limited by their component cost (not that they weren't after 1.0 anyways) completely nullifying the only advantage the Falchion had. It lacks the damage or mobility to serve as anything other than a glorified armored jeep, and is one of the precious two MPF combat tanks that Collies have. A terrible but "cheap" vehicle means nothing when queues and infinite components means that the only thing limiting the amount of tanks that can be fielded is the number of players in hex.
Most facility variants for Wardens are usually side-grades to their already fantastic MPF tanks. This is not the case with the falchion where the spatha is a strict upgrade over it and is generally considered to be comparable to the silverhand. There are really three ways to go about trying to address the falchion existing solely to complicate Colonial logistics:
1) Increase the cost of all tanks drastically so the falchions economic bonus actually means something (most people probably won't like this nor do I).
2) Rework the falchion into a decent vehicle like a tank destroyer of some kind maybe, and increase the cost to be on par with other MPF tanks.
3) Remove the Falchion from the game and put the Spatha in the MPF for 155 rmats like the Silverhand.
