Personally, I don't think making sidecut and silcut available to all weapon types to be the way to go. Both are pretty fantastic basic-attack mobility tools on their own, but making them universal undermines the uniqueness of them to me. Universal usage of both removes one of the few reasons to even consider Vent Petale as well, so I think that the weapon types that are compatible with them remain different.

My idea would be to make sidecut a sword skill usable by daggers, and silcut a spear skill usable by axes. Swords and daggers are quite similar to each other in the same way spears and axes are both polearm-type weapons, so it opens up more build options without killing the unique identity of the skills.

Both of those skills are so simplistic in their nature (a reflection on the design era of early sl2 ) that hold design space hostage.  Move in line and hit with basic attack is not something that should ever be unique to a single weapon type.

Vent petale is a absurd joke anyway. Ghost encourages axe+sword. Kensei punishes you for equpping a non katana (and there isn't a 5* katana to mutate into a spear), and firebird is 100% spear. Vent petale should be changed to 'equiping weapons of different types.
