I wish the loot system was more like an rpg. As it stands it's weapons only, you open a chest or loot people and you NEVER get outfits or anything, it's always weapons/money. Then the outfit variation itself is disappointing when it comes to numbers, as the vast majority are "recolors" mainly.
It'd have been great if they broke outfits down to parts, so you have a chest piece, leggins, gloves, pauldrons, hoods/helmets, etc. Then have these in the loot table along with weapons and other things. Then allow you to customize them even more with dyes or such.
I do like that they kept outfits cosmetic rather then going for stat-based, so you can wear whatever you think looks good rather then what has the best stats.
