Seeds should deepen from the field AND players hands when a team scores. It’s far too easy for a team that has the advantage to place 3 or even 4 seeds immediately after the next round begins.
I get that throwing them was a design choice and it takes teamwork to get a whole side to group up and daisy chain throws but at least have the remaining seeds respawn so the whole match isn’t a throw away for the other team, pardon the pun.
I’ve been on both sides of this and it’s far too strong for the game type is intended to be.
