I couldn't find a post about this, so I thought it would be a fun way to show off some of your favourite aesthetics for your heroes, since there are so many in the game. I'll start with four early heroes:
I've been using this combo ever since the wolf mount became available. It's quite possibly my favourite combination in the game.
I haven't played Diablo 3: Reaper of Souls on the PC, so I don't have the classic Malthael mount, but this combo works well for me.
Moving onto a healer, as a Metroid fan, I can't pass up on this tint. The Space Lord mount's third tint complements it well.
A classic combo, in my opinion. It's tough to beat, but I also don't like many of Kael'thas' other skins...
Let's see what the rest of you have to show.
