LOL yes lets make 1h axes unbalanced for realism: then we can add feinting with massive 2h axes and poleaxes instantly dislocate your wrists, cause realism, then we can arbalest reload times quadrupled, cause, your know, realism, then we can have any injury to a horse's legs cripple it, spewing the rider for, you know, realism, then we can have players intantly killed when their horses is killed and they smash their face into the floor at 30 miles an hour, for, you know, realism.
I could go on but 2 things to consider: 1/ This is game hugely unrealistic
2/ Im surprised when you cannot see the differences presented by 1handers, which include things from knockdown weapons which also have pierce damage WITHOUT changing modes, and swords that can outrange 2handers while at the same time are faster...
