Weapon swap would make sense if both were not linked to skills.
In EE, You have skills for weapon, so there's not much sense to change your weapon, if you have for example +5 in double wielding, there's no point to put sword & shield...
I never swapped my weapons in 200+ hours gameplay.
Although alternate combinations could be good if the skill system is the same, annoying to have to change my stuff while crafting/selling.
