Would you be willing to pass comment on my contention that 2-handed swordsmen seem to be performing well below their stats? It would help if I knew if I was the only one finding them a bit UP.

I do not think they perform below their stats. I upped attack of Zweihanders for 7 points (now they have attack 21, defence 11) and tried them against Sword and Buckler men (attack 13, defence 19) and they usually managed to beat them. They have charge 6, compared with SBM 3.

They also have Skeleton compensation factor 1.3, whatever it is (probably some bonus number because of their slow attacks)

I compared them with SBM because both are late era units with the same building requirement and also with the same upkeep.
