yea zenith, this has nothing to do with requirements, its a wording question
i believe it is fine as is. the description is suggesting that you need to have the intelligence to wield the weapon properly. you may have tons of dexterity, but intelligence is involved in knowing your weapon, weapon displacement, location, where its going to go when you use it, etc, and in order to not cut yourself, you need to have that spatial reasoning and capacity to wield it properly. therefore, the description is fine
