I’ve been farming a particular vanilla dungeon for about a week now, which means I get a lot of the same loot, including green and grey BoE’s.
Many random drops, especially grey gear, will have the same appearance across different items. This is indicated by the tooltip “You’ve collected this appearance, but not from this item”, when you’ve already added that appearance to your collection.
This made me curious whether people generally add the same appearance from different items, or instead opt to vendor or sell them.
For me, the tooltip triggers some sort of completionist instinct in me, so unless the item vendors or auctions for a lot of gold, I’ll probably (re-)add it to my appearance collection. Although this is easier to do when the dungeon you’re farming results in gear that mostly vendors for silver anyway.
