I think there's very very good chance of SEN making it, but after their performance at champs, and them not practicing for weeks makes it hard to believe that they'll be top of Group b.
My predictions
Group 1: 100T C9B XSET The Guard
Group 2: NV SEN V1 NRG
Group B's 4th is hard to decide since rise looks shaky in open qualifier. And I'm in NRG hopium because it seems like they've been practicing and grinding Tier2 tournament alot
