I like this change, except when it comes to a higher seed coming up from the loser’s bracket.
For example, in a 4 team regional, if the 2-seed wins its first two games and then faces the 1-seed who has fought back out of the loser’s bracket, I think the 2-seed should have the home field advantage in that game.
But if the 1-seed wins that matchup to set up a winner take all game, the higher seed should get home field advantage for that final game.
