hehehe

Since DRX announced Flicker (wouldn't make sense to not use him if he's already been announced) and Flashback's comeback for stage 2, I believe

Hyunmin (Duelist)
Mako (Controller)
Freeing (Senti/Initiator)
Flashback (2nd Duelist/Senti)
Flicker (Controller/initiator)
I can also see Flicker and Flashback switch roles between 2nd duelist (yoru/neon) and controller (viper).

foxy9 is staying on sentinels role (his recent ranked games shows)

It's cuz of FUT Esports unable to be in Group D due to Team Liquid. So they had to move DRX to group D and FUT to B.
