with MR 24 or 16 or whatever it would be better. dota matches usually last like 30-40 minutes, sometimes even 25 minutes.
if you look at this year's IEM cologne, there was a bo3 between astralis and navi. map 1 was 55 minutes, map 2 went to two overtimes and 1h 34min, and map 3 was 45 minutes. maps 1 and 3 were clear victories, yet they took longer than most dota matches
if you look at epl 13 finale between heroic and gambit, the whole thing took 7+ hours. I don't hate bo5's, but it was bit much
