I remember when Acend (then RYE) played against Rix.GG in open qualifiers for Challengers 3, they lost 1st map, they were losing 9-12 on 2nd map. Rix.GG could have won only 1 round, hence winning the series, and the storyline would be completely different.
But then something changed, Acend comebacked 2nd map, destroyed Rix.GG on 3rd map... And now they are here, in semifinals. Amazing.
