They are usually louder than the stream I was watching, which makes it really annoying. And they play it in multiple blocks during Blast sponsored content that I may enjoy, but can't watch because of the ads. In case of the Blast stream they actually break my player, as it will literally not turn to the actual stream for some reason (countdown top right just stuck at 0:22). During the Elisa tournament it was only when I opened the stream, so it wasn't that bad.
Meanwhile Blast preparing their survey to ask me if I saw their sponsored content lol
