I personally use the Scottish Sword, and therefore instantly notice when someone else uses it as well. In all truth, I see it around pretty often..
I am not an agi build, but 80 reach isn't hard to deal with. People do tend to stay away from it because of its reach, but there are others who enjoy lower reach weapons, like myself.
I love the Scottish Sword how it is.
However, adding just one damage to thrust? Raising the price by 750 gold? Why?
Just use the Short Sword, the stats aren't far off and it would work for your low strength builds. No point changing them.
As far as appearance goes, I would just fix the sheath. It bothers me how it floats half a foot away from my hip.
I am a dedicated Scottish Sword user, but I hope your changes don't pass. One more damage for thrust? At the price of more upkeep? I would hardly notice the difference, true, but then why implement them?
