There are way too many redundant weapons in my opinion. In particular, I think the knives category kinda sucks. For one thing, none of them have backstabber, which is instead only on two uncommon items. The d4 damage is still so bad there's almost no reason to ever use this whole weapon category, as it has been in every edition. Starknife seems like a weird weapon to be on martial instead of exotic (plus it's kinda dumb that it has deadly), while the kukri is uncommon for basically no reason (P.S. why does it have trip instead of forceful or deadly). The only one I kind of like is the main-gauche, but since it's martial I don't see myself using it on either of the classes I'd want to (rogue and bard).
Other than this, light mace sucks. I don't think anyone has ever asked for a finesse mace that does less damage. Katana is literally a more expensive longsword, it should have deadly or forceful instead of versatile. I still don't really get why Bo staff and staff are different weapons, but I guess it's nice the bo has reach and parry.
Also, a lot of these new features are cool but underwhelming. +1s don't really feel like much on the tabletop, even if they are mathematically significant overtime.
