Just learn from the videos how to beat Yuri, there are tons of videos now on youtube , yuri is OP but it has his weakness which you can exploit and still win as sov. as allied still v.hard to win yuri.
Rank 1 of last month end up rank 4? What is the credibility of this Quickmatch then ?
Anyway round robin is good too, double elimination is fine too, but please next time don't allow players like andy who run away after getting humiliated.
