We have so many animation packages for 1H-2H swords, we also have some plugins for melee system but we don’t actually have a functioning melee system for building action rpgs.
It would be nice to have one. I’m not even talking about Dark-Souls style melee combat which is extremely advanced. Up to the point, that every single weapon has different animations, reach, etc.
Even something smaller, like in Skyrim, Oblivion, Gothic 1-2-3, would be nice to have.
