Bruhhh...
Here is what I said earlier: "He also was a team MVP in first SEN game and match MVP VS V1." Now, how is that not one of duelist's roles? Typically a role of a duelist is to create space either by taking down the enemy or pushing the enemy out. He does it well imho. Besides fragging, he also adds value to the team in other aspect of their game. Ffs the dude just signed with Fnatic like what... 2 months ago? I still think he is exceptionally good at his role. And I really don't know wtf has happened to his mouse today, if the rumour is true. But it is clear that he underperformed today.... And forgive me for saying that if not for this Derke, Fnatic would have never qualified in the first place.
Anyways, you don't have to agree with me... Impact can be measured and you can find it in charts. Also you'd need to analyse his match history since arrival:
