How double elimination normally works is that the upper bracket winner has to be beaten twice by the lower bracket winner. But you kinda can't have that in CS because of scheduling and stuff, so there's a map advantage instead
1-0 advantage is too much imo.
the upper bracket winner should get map pick/chose start side advantage. with that in mind the team from the lower bracket could still prepare, would still make up for good games.
Ok so there is 2 possible ways of future right now for ESL.
1: Boombl4 eats more pizza and singing more songs so NAVI 0-3 BIG
2: S1mple finnaly gets gold nova 3 in matchmaking so NAVI can take single map and 1-3 BIG
