I'm probably sleeping on MaKo. The only reason why less isn't S, is because as good and consistent as he is, I don't think he can win games almost completely by himself like Aspas can, but yeah, Less should probably be S too, some of his clutches are nutty.
I should probably explain that IGL's and teamwork probably played more of a factor than gunskill in my tier list. Like FNS/Boaster/Saadhaak aren't REALLY A tier gunners.... On their best days maybe slightly above average pro players aim wise. So High B's, and they probably play around low B and C most of the time. That being said, They deserve A to me, because all 3 of those players can lift almost every single player on there roster to higher tiers if they are calling well. For Example the NRG players, if FNS and the team are hot. It becomes a team full of A tier players and an S ranked star+IGL... a team on paper that can and has won international tournaments. But on average aren't going to dominate any single league or tourney run, it's always going to be hard maintaining that higher level performance, they just do it consistently, because of FNS.
Same can be said with Fnatic and Loud, they have some of the best IGL's, but the difference there is most of there players are already S or A tier, so the boost they get literally turns those teams into monsters in god mode.
DRX lacks that, sure I don't think anyone on DRX is below average, but they never win these tournaments because they don't have a god mode that makes them able to compete at the highest most tense moments imho. So that's why I left most of there players in A
TLDR: I'm a nerd for valorant, Mako is pretty good, I just thought about my tier list oddly when I made it.
