I have seen people complaining about not having a dagger category and whatever if something is magic or not, and I feel that everything can be avoided if the weapons are categorized based on their damage type instead.

Cutting (From bladed, lighter weapon) Blunt force (From mace and hammers ) Bullet (Non-magical bullet) Wave (Non-magical explosion, sound wave, wind based attack, hot gas, etc) Magic (From Tome, orbs, dark matters/light matters) ETC

And the confusing one-handed, two-handed can be replaced by "weight"

As far as one-handed or two-handed is concerned, I look at the relative size of the wearable on the HA if it has one, I examine the grip, and also read the description if it mentions anything about being heavy. I've also played a lot of Dark Souls, so your double-sided axes, hammers and greatswords are naturally going to be heavy.

Not bad for categories, but a spear does not really cut. It pokes. xD Maces are also specific in doing two things, cutting and blunt force.

I remember Lance and Gun Lance, in Monster Hunter are classified as "Pierce" too. I think it will switch between deal Blunt damage or Cutting damage that will deal the most damage and is very useful when dealing with heavy armour monsters. So, I agree.

The same thing about Sharpening Hammer meme in Monster hunter, because of Hammer weapon types are some kind of spikey mace, and would explain why it needs to be sharpen.

The only weapon that I have no clue what to list are the gunblades we have. It's a fictional weapon. xD

At the end of the day we have no idea what they are planning on using the categories for so it's kinda hard to judge them.
