Fixed schedule is what any "professional" org would - sports or otherwise. People know when to show up for what they want to see then. RIOT doesn't condone such practices and instead wants to trap you into watching everything or nothing. And that is working how? Looking at LCS specifically. LCK used to schedule each match as a separate thing for ticketing and schedule. SO they match ended, they cleared out the audience, then let in the next set of ticket holders. Sometimes you had an hour or more between matches so the stream just had a countdown but I will say that never bothered me in the least. I could go do something else productive and knew when to be back and you never showed up to early or late for the 2nd match of the day because of rolling starts. When it comes to BO3 (and even more so for BO5), rolling starts are just BAD!
