Then we are back to square 1. Adding in specific fighting styles for a weapon and only allowing me to have one pigeon holes me into only ever being good with a single weapon. Even if you keep the old ones if yours are actually superior as I presume they would be as they only affect 1 weapon instead of all then that also pigeonholes me into picking a bad mechanical choice to play the character I want. You are not empowering me with options. You are restricting me with options.
So basically, you'd rather play a character with boring mechanics and interesting aesthetics than a character with boring aesthetics and interesting mechanics.
