Easy or not, this is the best option for a tournament. BO1 would def feel too quick when this is over. Also imo nothing wrong for a dominant player to inevitably win (every) tournament, people do like to see dominant performances, and I believe this increased the popularity of many sports/games.
Regardless, someone would need to step up if we don't want that to happen
This is why I left the option open for the tournament to be played on a single day, on Sunday, that way all what a player needs to do is to show up at the scheduled time and then play the tournament, and the tournament would finish quite fast if the BO1 option is chosen. Also if one player doesn't show up there is the possibility of finding a substitute in lobby.
