What are you waiting to release a mobile version of HOTS?
It’s the perfect moba for mobile platform, fast games, different from the others with maps objectives and hero progression in game.
I bet at least 80% of the players that have ever played this game will be excited to play a mobile version. And with a little effort in the marketing department you will captivate a lot of new players.
You have Pokémon united, that also has a different approach of the traditional mobas that does not have half the quality of HOTS and still manages to retain a large playerbase.
You already have a large and balanced heroes roster, maps, skins ,mounts, etc.
A huge player base that loved the game and stopped playing because of the end of competitive gaming and all the public relations mess you guys created. Where us players, where expecting the game to close doors at any moment.
And a lot of new players that play mostly mobile games, which is a ever growing community.
You have everything to go toe to toe with other mobile mobas.
