Here’s what I want to see - possibly in a St Patrick’s theme release.
Rainbow or leprechaun Diablo skin where his fire is also rainbow. Really anything that makes any character have a rainbow, gold, or shamrock/lucky type skin would be awesome. We already have mount options with similar themes that so having a character’s skinmatch would be nice.
Seeing more characters as fantasy creatures in general would be better. I know most characters have fantasy elements anyway but I want it for stuff like the overwatch and nexus crew too. I love the Lunara rainbow unicorn portrait, was that a thing a while ago? What about fairies, Mermaids, gnomes, nymphs, zombies?
I’m probably already saying stuff others have suggested but when I brought up the rainbow breathing Diablo thing in a few games people were on board.
