I have checked all stats and I have thought about this, that doesn't mean my list is perfect.
For example, with Jame and huNter you are right and they will not be in that position or even in the ranking at all, who knows. About s1mple, I disagree. If he doesn't get the first place, he will get the second.
Brehze has played better than Magisk and NAF and I don't think I got the wrong.
About cerq and jks, maybe they will be a bit higher but I don't think they will be much higher considering the other players...
And about yuurih, I agree. He probably won't make it, instead, Brollan, Ethan or even frozen, kenny or kcserato will make it instead.
I didn't want to sound like this is for sure or I have it all under control, I just tried my best. HLTV doesn't say in public the factors of why picking one instead of another (it can depend, they migh give more importance to Big events instaead of MVPs, or against TOP5 instead of map played etc...) and we don't know for sure so we can't possibly make a 100% accurate top 30. This was the ranking as I think it will be, thanks for the feedback
