i just finished a long progression fantasy series and it has a tournament obviously and it was double elimination! i was very excited, however we never saw the loser bracket fights and the result wasn't even mentioned so it was kind of pointless. i guess it was the type of double elimination where the winner of the losers bracket could only get 3rd which is the worst version of double elimination. we need to see more innovation in tournament arcs. tournament arcs are the best kind of arc you can have but we need to be hungry, keep innovating the tournament arcs!!
