I’ve played a lot of Battle net games by installing battle net in lutris, then installing the game I want to play there. There’s a lot of scripts you can find for installing particular games. I can’t speak for whether HOTS works, but I played many many hours of WoW and Overwatch (before 2) that way. It’s annoying using a launcher to run a launcher to play your game, but it works.
