This is by role, so IGL not counted. But I think FNS = Saadhak = Boaster > Redgar > Ange1 = Boostio
Team 1:
Aspas = Derke
Less = Alfajer
Sacy < Leo
pANcada >> Boaster
Saadhak << Chronicle
Fnatic still better overall, but this is probably the closest, closest indiv skill, firepower and chemistry.
Team 2,3
Something / Demon1 <= Derke
Suygetsu/nAts <= Alfajer
Shao / Trexx/ Cloud <= Leo
Sheydos/Zyppan < Chronicle
Redgar / Angel1 < Boaster
Close but Fnatic better in every role, except Leo = Shao, and prime Nats = Alfajer but Nats has yet to hit Berlin prime again. Prime Suygetsu = Alfajer, but same he hasn't hit Copenhagen prime since.
Team 4:
Demon1 / Zekken < Derke
Victor / Leaf < Alfajer
crashies < Leo
s0m / Marved >> Boaster
FNS <<< Chronicle
Just worse than Fnatic.
Team 5:
Demon1 / Zekken < Derke
Ethan < Chronicle
crashies < Leo
s0m / Marved >> Boaster
Boostio < Alfajer
Worse than Fnatic.
Team 6:
Something <= Derke
Jinggg = Chronicle
d4v41 < Leo
MaKo >>> Boaster
BuZz / f0rsakeN < Alfajer
PRX + Mako slaps, but they can only really play double duelist so they aren't close to as flexible as Fnatic.
