Would really like to see all matches be B05 given Valorant matches are very short. 2 matches doesn't seem long enough given that you just need to reach 13 rounds to win and the overtime is only +2 rounds every time.
All games BO3 is good enough, with a final BO5. Imagine trying to play a major with BO5 matches and technical delays etc. People will just stop watching halfway through, that's like a full afternoon + evening commitment per match
A football game is 45 + 45, and that's roughly what a valorant match is unless it goes to 3 maps.
