Before raiding, it should warn for follower or sub-only mode
If I am choosing someone to raid at the end of my stream via the Dashboard, I think it should tell me if the stream that I'm about to raid is currently in follower-only or sub-only mode (i.e. in-line in the list as I search for them, or after already selecting them).
It can kill the hype of some raids if I'm already following or subbed to the streamer I'm planning on raiding and then the majority of my community can't type or join in the raid without following/subscribing.
It feels like a minor feature which would have huge impact and be very beneficial.
