I'm not sure I'd be willing to throw any definition of Warband in the problem bucket because they are all known and easily identifiable. The problem is Ninja, Shinobu, Oniwaban, Saito, and to a much lesser degree the vast number of capable Camouflage melee fighters. Those that can Engage reasonably far from an unexpected direction, particularly since there is no reactive turn weakness for melee. No one would ever play TAGs again. Or anything that's not essentially order spam. If there was a risk of running into Dahshat, JSA, Yu Jing, ISS, Ikari, Druze, or literally anything in Mercenaries extra, simply because if they put Saito in the correct place, they have a very, very, high chance of Engaging you expensive shit and you'd need to waste a lot of orders on a Sensor unit to get them freed from him.
