Hi guys, I'm the one which implement streaming on Firestorm.
I really think we don't add Hitbox to our platform.
I'll try to say you why with details :
It's not as no such works as you think. The actual system will needs a complete rework because we used the Twitch API to get streams. And if we add HB too, it needs a link to their API too. Plus, there are a lot more twitch users than HB and our teams will only works with twitch streams.
So... there will not be an HB implementation on Firestorm. Sorry !
Have a nice play.
