NFT's would be great if used correctly. I don't see much use for them inside blizzard game, seeing they can just use auction houses and trading systems; but I see a lot of people burning the concept of NFT based on their application on .jpeg's.

An NFT can be ownership over a digital item, like say a WoW expansion. If you don't play it anymore you can pass it on to a friend, just like you could with say a Call of Duty on disk.

Again I'm not saying Blizz games have a clear spot where NFT's could bring something valuable, but judging in against their .jpeg application is in my opinion closing your mind for the potential it could have in other scenario's.
