It will be a 4 pot system. The pots will be the following
Pot 1: Fnatic, TL, EG, PRX
Pot 2: FUT, NRG, DRX, EDG
Pot 3: Giants, BLG, Loud, T1
Pot 4: NAVI, KRU/LEV, ZETA, FPX
Each Champs group will have one team per pot. They were seeded by Tokyo Placements and LCQ finishes.
Looks very balanced to me. Loud in pot 3 and Navi in pot 4 are the ugly draw everybody would like to avoid whereas the chinese 2 & 3 seed and FUT in pot 2 seem like lucky draws.
Strongest possible group: FNC, NRG, LOUD, NAVI
Weakest Group: TL/EG, FUT, BLG, FPX
At this stage i believe it is possible for teams of the same region to be in the same group. That is the part i do not know for sure though. Maybe it is just EMEA
