I'll start with a few
XSET: Bcj
TSM: Wardell
Liquid: ScreaM
V1: Zellsis
it's difficult to determine a BEST player, as what @Casual has said above^^ are mainly all duelist players, can you imagine what some other players like 100T Hiko or FNATIC Magnum on a duelist, however we don't know.
My thoughts are;
SEN: SicK
100T: Hiko
V1: Wippie
Fnatic: Magnum
Liquid: Jamppi
Envy: FNS
Noble: Zekken
C9B: Leaf
TSM: Subroza
drone is better when he is on sova, but all sova mains are able to get high stats because they often need to stay alive for post plant. When drone plays pheonix he plays horrible, it is clear it isnt for him and he should play sova. The problem with roza is that he is sooo good onn omen and legit had top 5 acs at vct on omen, but can't play as well of a role when on a duelist

idk that's all i could think of.
Edit: bolded teams mean they played in masters Reykjavik
lmao gtn best player. jk. Also I think Yacine is the best player on guild though. I'm too lazy to look at the rest of the list though. Your APAC list is pretty decent though considering this platform is very NA centric. There are a few ones that are not quite correct but I have no idea how Reject or Fennel play so your list is probably better than mine. I don't know much about the LATAM/BR scene to know who's the best player on each team there. Also I respect the T1 flair but please respect c9. Like big sadge that people don't realize that c9 only barely missed qualification for masters. Leaf is def the best in c9 though.
