S: EDG, TH, LEV
A: SEN, DRX, GEN
B: FNC, G2, PRX, KRU
C: TE, VIT, FPX
D: BLG, TLN, FUT
B is harsh for FNC no? Or maybe too lenient on PRX/KRU. This is about their performance at champs, including expectations in extreme cases such as PRX
What I would have (tiers are not ordered):
S: EDG, TH, LEV
A: GENG, SEN, FNC
B: DRX, G2, TE, FPX
C: VIT, FUT, TLN, PRX, KRU, BLG
(no D tier because I think the difference between C and D is just semantics here)
