Gear seems to have attributes applied fully randomly. So you end up with staves that have katana mastery. Wish there was some limiting of certain attributes.

Hey there, the decision for that is mostly so it opens up build variety. for instance if you're mostly using Sword Abilities but also use Dagger Abilities, you (potentially) could aim for a Sword with both Sword Mastery and Dagger Mastery on it. Also when you upgrade the Blacksmith fully you can replace a modifier with any modifier of your choice
It just made my start really frustrating when I am constantly just in garbage gear with random modifiers on it. I think I found maybe 2 pieces of gear that were matched to what the item is. I still say that if you want that kind of build with different mods you should make it after you unlock blacksmith and that gear shouldn't drop with such random modifiers. Or the weights on getting a staff with daggers should be much much lower than a staff with staff mods.
