PTO for top tier partners
One of the major complaints of top tier partners (ninja, timthetatman, etc.) on other streaming partners has been the inability to take time off.
What if you offered "paid time off" for these top tier of partners by promising to renew any subscriptions that would expire during a vacation that was during their allocated vacation days (could allocate a standard 2 days a month or vary it up).
Partners would feel more secure, be healthier, subscribers win, but it would cost some money on mixer's end to maintain that subscription. Instead of renewing the subscription, you could also put it on pause during the specified pto dates.
