I believe V1 can beat envy, they have a favoured matchup given that ascent haven and split will prob be the maps played. 2-1 for V1 in my opnion, maybe 2-0 but i believe envy wins haven.
But stomp C9? I dont see it, if C9 and V1 meet i think C9 takes it 2-0, also because of favoured matchups. V1 always bans Bind and C9 have to watch for V1 ascent, looking very scary. So prob the maps played will be haven icebox and split, wich cloud9 plays all of them pretty well and have been on a roll
and if V1 meets Sentinels i will still prob be 2-1 for sentinels, the maps will prob be the same as if they played C9, and Sentinels showed that they arent very good on icebox, so i give it to V1. But Haven and split i give it to sentinels like last time they played
