Each tier is in no particular order.
S: FNATIC, LOUD, DRX, NAVI, NRG
A: Leviatan, Talon, Furia
B: GenG, FUT, Vitality, TL (for now), TS, PRX, EG, Giants, Sentinels, 100T
C: ZETA, GE, KCORP, KOI, BBL,
D: TH, MIBR, KRU,
F: Detonation, RRQ, T1
Teams Without a Complete Roster: C9
Debatable Choices:
NRG: I think NRG is S because they were a couple of crazy clutches (by LOUD) away from advancing and most likely making the playoffs, I think they could compete with any of the other S tier teams.
T1: The roster is extremely underwhelming and I really dont see how they will perform much better if they keep it the same.
Sentinels: They lost some very winnable rounds against FNATIC and I think without those its a really close game, compared to 100T's performance against FNATIC they looked objectively better and I think the firepower of the roster is not to be understated (except dephh).
Furia: Toe-to-toe with the best team in the world.
EG: lost to Talon but choked both maps, I think they could've won that matchup.
Edits: Moved 100T and SEN to B tier
Let me know what you guys think about these rankings, thanks!
