By the way, exactly the same thing occurred in Challengers 1 with XSET and Gen.G.

XSET got lucky opponents and won NRG and Envy (both were weak at that time), meanwhile Gen.G won NRG and then had to face SEN, who accidentally dropped to lower bracket after losing to LG in initial match.

Double elimination bracket has its own disadvantages like these. But it's still better than trash single elimination that EU used in Challengers and Brazil will use in Masters.
