I know a lot of people made their own tier lists, but 95% of them are from baiters with no brains. Here's a based tier list, the based placements for a team are bolded:
S - FPX, Optic, PRX
A - FNATIC, DRX
B - EDG, 100T, LOUD, TL, Leviatan
C - XSET, KRU,
D - FURiA, XERXIA, ZETA
F - BOOM
EDG is gonna be the dark horse in this competition, it all depends on how well EDG can adapt to structured play styles from the S and A tier teams. I believe there's gonna be a lot of upsets due to complacency among those in the previous masters' A and B tiers, which is why LOUD is rated lower and DRX and 100T is rated higher. I also think that 100T is much better than XSET at the moment due to each individual 100T player contributing to their LCQ success. I believe TL is the worst EMEA team there, but they can still easily make it to playoffs. Finally, I think ZETA is going to do poorly since TENN isn't playing.
P.S. The teams in each tier aren't in any individual order, I think they could beat the others in that tier on any given day. It's just a coinflip with them. S tier is maybe the only tier in order.
