This game clearly thrives on being fun for everyone, not just interesting for the ones caring about the competitive scene, which is a vastly small amount in comparison to its playerbase.
Streamers and youtubers are definitely a big part of the success, I'm not denying that. But they're not necessarily part of the competitive scene. In fact, the entertaining streamers such as Kripp, Forsen, Reckful and Reynad are often gathering tons of more viewers than the competitive ones, and they are rarely to never in tournaments, but rather just... entertainers. Because HS is a great game for entertainment due to it's RNG, the slow pace which benefits viewer interaction, and the accessibility.
Now compare that to the competitive streamers. Firebat, for example. He isn't anywhere near any of the forementioned in viewers. Neither is StrifeCro or Lifecoach or any other streamer that focuses on playing competitively. Kolento might be the one exception to the rule, but entertainment streamers are hugely more popular than competitive ones in general.
So fine, if you argue that all streamers are part of the E-sports scene somehow, even the ones purely entertaining, then yes, I would agree with you. Without all the streamers and youtubers, the game would be marginally less successful. It would probably survive, but not be the big hit it is today.
HS could stop being an E-sport any day though, and nobody would really care. There's enough Forsen gachigasm, Kripp toptecking THOSE EXACT TWO CARDS, Reynad PJSalt and Lea ***slips to keep the community going for a long while.
HotS dug it's own grave by trying to enter the fiercest competitive genre ever, and doing so while presenting itself as a vastly dumbed down variant of it. There was never any hope for it really, I don't think it's a fair comparison to make.
