Grinding out those Warcraft matches in Heroes of the Storm for the in-game mount!

I would like to add Baten Kaitos to the list. It’s a unique rpg with card mechanics. It is quite fun and can be challenging as well!

I just don’t understand why they don’t invest a few hours (I know it’s more than just a few) into getting this stood up and making some more money. Runescape has done it, Everquest has done it. Why not Blizzard and Warcraft?
