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…
This can happen in Swiss. If BLG makes it to the finals and beats T1 3-2, they would have an overall losing record of 3-4.
