Rework the Ad Incentive Program
Currently, the Ad Incentive Program presents you three offers every month. It's on a take it or leave it basis. I find there is a big issue with this though. The amount of money you are offered is fine. The amount of hours you are required to stream for a month is fine. The thing that doesn't make sense is the amount of minutes of ads per hour you are required to run.
I have received offers in two months now where the lowest ads per hour requirement was 4 minutes, and I have even seen some people with their lowest being 7 minutes. This creates two problems. Some people may be willing to run ads, but they aren't willing to run THAT MANY ads. It seems counterintuitive to require them to run too many ads per hour, such that they just decide to decline it and run no ads that month.
The second issue is the longest time an ad break can be ran for is 3 minutes. It works really well to just take a break from the stream once per hour while the ads are playing, so that no one misses any of the content from the stream. When the minimum ad incentive offer is over 3 minutes of ads per hour, it is impossible to just take a single ad break per hour. For example, with 4 minutes per hour, I am required to take two 2 minute ad breaks every hour. It just doesn't feel right to take a break from the stream every half hour, so I end up having ads playing while I am presenting content.
I think a better way for this program to work is as follows. When you receive your Ad Incentive Program offer, it will give you the hours required to stream that month, along with a price per (minute per hour) of ads. Then you can choose how many minutes of ads per hour you wish to run that month. For example, it may say stream for 100 hours at a rate of $100 per (minute per hour) of ads. So I can choose to run 3 minutes of ads per hour to earn $300 in that month, or only run 1 minute of ads per hour to earn $100 that month. Or I could even choose to run 10 minutes of ads per hour to earn $1000 that month.
I do think the Ad Incentive Program has been helpful for earning more revenue as a streamer, but it's still not ideal. This change would at least give a bit more control to creators as to how they run their stream.

There is exactly zero chance I ever run more than 3 minutes of ads in *one* break per hour. There's more chance I ditch any affiliation with Twitch and stream for zero revenue than for that to ever happen. I will not run more than one ad break per hour and it will not be longer than 3 minutes. I wouldn't do it even if you gave me 5k per month.
