The LCS circuit as a whole has always tried to model itself after sports. In which case, I don’t see why the league needed to switch back from bo3 to bo1. Even the most hardcore sports fan is not going to watch every game of the regular season or every match in a tournament. The only people that do that are analysts, journalists, and maybe coaches. I don’t know why League fans are happy that they basically hampered the level of competition so they have a stronger sense of having watched everything. It’s basically an illusion, it’s like assuming you know everything because all you have to learn is arithmetic instead of the entire multiplication tables.
On the other hand, it’s clear that Riot have never had an emphasis on competition and to see who is the best, so there you go.
