I think it's pretty ridiculous that they are still playing this match at 4:30 in the morning. Maybe the solution isn't to get rid of all Bo5, but rather, reward players who win the first two sets. I'd much rather see them be rewarded a 2-sets-to-none win, than to have to play additional sets (this will come handy later in the tournament). That saves a lot of time and energy, and would get rid of most of the ridiculous overnight finishes. To me, if a player doesn't win either of the first two sets, they don't deserve a 3rd set.
