What if Blizzard would also make hero collector RPG game similar to Raid: Shadow Legends.
I’m not really into mobile games, but this is first one which is quite addictive.
I mean Blizzard also has much richer content. From Warcraft alone there would be like hundreds of heroes and probably sticking to it would be just enough (so not making it like HotS).
Hero collector RPG is much more fun than card collector game, therefore would be much better than Hearthstone.
Raid is not bad game, but it would be more awesome to see legendary heroes like Jaina or Illidan. And Blizzard usually doing much better when releasing game in already occupied genre, like HotS in my opinion is much better than LoL or Dota.
To not disappoint PC users a client with “much richer graphics” should be implemented as well.
