Dunno. Blizzard use these "influencers" as their community managers instead of hiring their own ones and making them work properly - not just silently sit on forums and do nothing. Blizzard assume, that if streamer with 100k subs tells X and 100k subscribers like it, then this X is good for 100k players. But they're just partially right. Game has much more problems and more serious problems, than they say. Blizzard still don't understand, what casual players want. They treat casual players, as solo players, who want souls-like solo challenge or some long term grind. Completely wrong.
