So one handers are half the cost as a 2 hander or polearm...because they supposedly would get damaged 1/2 as much?
Well, people using 1handers usually have either a shield, bow or crossbow - so they also might pay for another item. Sure, that one will not cost as much as a 2hander or polearm, but still. There are also shields (steel shield), bows and crossbows using 2 slots so those people pay a bit more as well. And archers pay more often for their arrows anyway. It is pretty much balanced and imo 2hand and polearm users should have more disadvantages anyway.
Until now I was always fine with repairs, however whenever I used a horse I had to pay for it 4 out of 5 times.
