I find the more indepth streamers have chats more interested in in depth chat, such as being concerned strategy plans, the effects of gameplay etc attracts people to discuss the same. Whereas you have generally toxic people such as memb with chat shittalking players then crying whenever a mangonel shot hits two archers. You can either have a hype stream with toxic chat missing half the things going on in the game or a stream analysing things (Which you can see would make it more boring if you don't care about strategy) where a lot of the chat are invested in the same.
