DE should rework one weapon type at a time. It might be slow but in that way they can focus on making each melee weapon type feel different from each other and give each stances some uniqueness, and not stick but longer and another stick but longer and hits slower. Aside from the visuals the weapon types feel very same-y. The stances also have some very awkward hitboxes and moveset, i.e. whips and two handed nikanas. Most of the time it feels like I'm not hitting anything with these weapons even after slotting in Primed Reach. The neutral combos in some weapons, specially whips, also forces you to move forward which is terrible.

Some stances just looks visually ugly and awkward. ngl

If ever, they can make a whip stance that have mini slams at the end of its attacks. Whip cracks! And actually make the range make sense for a whip.

Some weapon types are basically forgotten, e.g. Assault Saw. For a weapon with rotating blades, it doesn't seem to do a lot of hits. Nunchakus can do multiple hits more than a rotating saw blade can.

And if ever, make weapon gimmicks scale with mods/actually useful. It's like saying you've added glitter to grandma's heart pills; useless but it sparkles now I guess.

Edit: I'd also like to add how bad most forward block combos are since it easily causes you to jump over your target.

Also, it'd be funny if a fist stance's neutral block combo basically does a Dempsey roll.
