First off, I am making this ranking with the criteria that performance is the most important, achievements close second, and the "carry factor" is lightly considered. internationals are much more valuable than regionals. As for LAN vs ONLINE, I'm not differentiating them if they're not international.
With that being said:
1 - cNed - Best player in the world, Very high rating, champs winner, masters 1 winner. Hard carried Acend through the year until champs.
2 - nats - Rating looks not so impressive, but he is by far the best sentinel in the world. High impact player, and most team achievements: Masters 1, 3(mvp) and 2nd at champs
3 - TenZ - Became a bit overrated, but still incredible player. Historic rating at Iceland & mvp, good rating in masters 3 despite losing first round, played bad at champs though.
4 - Yay - IMO a better player than TenZ, but played for ABX for a good part of the year, accomplishing nothing. Their ratings diff isn't much either. Definitely will be higher next year
5 - ScreaM - Arguably the best aimer in the world, but 2 downsides. 1 - Plays secondary duelist with reyna, but can't flex onto skye. 2 - When he plays the jett he is a liability in some situations. Still best reyna and top sage, and hope TL can not choke next year.
6 - Chronicle - Best sova in the world, solid flex onto smokes. He doesn't carry the team and his stats aren't the highest, but 2nd best player on the most dominant team.
7 - Derke - Underrated jett, top 5 in the world. However, people wrote him off after choking the GF in Iceland. Played very well at champs and gets a boost for that
8 - ShahZam - One of the top IGL's early on in the game. However, he is often held accountable for SEN's lack of adaptations to the meta. He's still played above expectations after switching off jett, but he's had his woes this year.
9 - keznitdeuS - Made all 3 international events this year, and IMO he was the best secondary duelist at champions. Still you can argue that LATAM isn't the most competitive of all regions, but he's proven himself. (P.S. First game I ever watched of him I thought he might've been cheating. Now I'm just impressed how good his crosshair placement is)
10 - Zeek - Inconsistent throughout the year, but at his highs he is the best in the server. Champions MVP deserves this last spot despite not having anything else.
