Not having to play extra matches or getting side selection is not a big enough advantage for someone who NEVER lost. What would they get out of it?
Would a bracket reset be good for viewership? Might be way too long for most people, and would lessen the stakes of the first set. If a team started with a 1-0 advantage that could result in a 2-0 dud of a final. I just don’t see many good solutions here…
If you bulldoze your way through a double elim tournament not even needing the bracket reset, 2-0 ing grand finals then you really didn’t need any advantage to begin with.
