Which would be a bit odd don't you think? The fact that the sect determines a person's combat effectiveness through single combat seems weird to me. There are many different types of talents in the sect, and excluding them here seems weird.
Team coordinated cultivator are just as useful to the sect and the Empire, if not more So, than single person powerhouses. It seems a bit inefficient to me for the sect to make the entire tournament 1v1 and reduce the effectiveness of these team players. That would be wasting the talent of good cultivator.
This isn't me saying that the tournament is gonna be team battles though. It's just me thinking out loud on how flexible the sect would be in accommodating competent cultivator who don't work so well in single combat.
Maybe there are alternative methods for these sorts of people to enter the Inner Sect, I dunno, but if I was an Elder i would try to be inclusive towards those who work best in a team.
