Ok if you want to pin your headcanon in...
At least don't spill your nonsense around.
Furthermore, if Stephen is right about sword user that other argument about versatility is also illogical, not that it isn't by itself.
Doesn't matter how many styles you have or how many features, you can be a swordsman independently lol.
At least if you are a consistent user then you are a swordsman. And by consistent not necessarily skill wise if what Stephen says is right.
