I think it would be possible to provide equivalent options for every weapon (and similar situations be handled in like fashion). For example (not suggesting this should be the rule, just an example): Every weapon gets a situation where you get advantage when wielding it. Maybe that requires some specific feat or whatever, but it is consistent across all weapons, and each situation is designed to be pretty close to equally likely (probably all of them are uncommon corner case situations, maybe daggers work really well when you are grappled, tridents might be really good against huge opponents, etc.).Well then at some point, what's the point of having choices be anything other than cosmetic? If everything did 1d6, you wouldn't have to worry about the issue at all. Yet that would pretty much suck because people like choices to matter.
Beyond that, it is a bit annoying to see specific 'paths' created which only allow for one weapon use tradition. Why does every Gish HAVE to be a sword user? Can't the rules just say 'weapon' and let the players and the GM work out what is cool to them? That would eliminate a LOT of this stuff. I mean, granted, sometimes there's a more substantial basis for it, and then my first point applies, there should be an equivalent for other weapons!
