The sub chats are my family, they make it so bigger streamers audience can actually engage and have conversations, by getting rid of the rooms it can make more people have anxiety, less communication between users and overall less activity. The biggest reason that i use twitch is because of the friends ive made in the chat rooms, but if the chat rooms are gone i will have to much anxiety to talk ever again which will efdect not only the streamers but also my well being.
