The main reason I stopped running mid stream ads is because it is MORE disruptive than prerolls if you do longer streams (12+ hours) like I do.
To put it into perspective, if I wanted to disable prerolls for at least an hour every opportunity I can I would have to run at least roughly 30 minutes of ads, that's ridiculous.

My suggestion is that we are allowed to accrue at least 2-4 hours of no preroll ad viewing, then after that time is up we could run midroll ads during a break and have things even out more smoothly for the viewers and the streamer.

In it's current state you are asking me to run 3 minutes of ads every other hour and that's really disruptive to the flow of the stream.
I couldn't even sensibly fit that into a reasonable break schedule, that's why I think it would be way more reasonable to at the very least be able to accrue 2 hours worth of preroll-free viewing, you could take a break every 2 hours without it being too disruptive to the flow of content.
