Wait what? Im not saying they are doing this to tohaa, but didnt yu jing lose a bunch of units to that one new na2 army? Im pretty sure it would be in keeping with theme for there to be new chaksa/kaauri/tohaa units in an na2 box that the designers felt didnt meld well with the base army and so were not released for the main army. Im assuming at least a few would be available to tohaa, to make tohaa players want to buy the box, but the design team can also say certain units are too good when teamed with makaul or symbiomates or whatever and leave a reason for tohaa players to move into a new faction (so they can use all the pieces in the box). I mean, it makes sense from a design perspective, and from a marketing one as well. Worst case scenario we can just use the new units as proxies for other things in tohaa if we dont want to change factions or whatever.
