Well you are also arguing that Fnatic have been doing recently when they haven’t. Before the tournament, Fnatic had only lost to teams like c9, liquid and Astralis and the astralis game was increadibly close anyway.
This roster is still relatively fresh and twist hasn’t had enough time to integrate into it to say that he is inconsistent, if the igl just learns how to implement twist so he is effective the majority of the time then he could be a force to be reckoned with.
Even though the meta and the style of the game is dramatically different to when JW was at his peak, he is still young and is has shown signs that he is able to perform on his old level recently and since he has shown that then there is the possibility for him to come back to his former glory.
Finally, the map vetoes were very stupid and also Fnatic right now are a really good anti-strat team but they can’t have this playstyle against basically unknown teams like vici and winstrike who both rely on star players showing up and getting mad plays rather than playing tactically. Additionally, I really believe that if Fnatic played bo3s against either of those teams, they would get fucked because they would be able to learn their play style and counter it and it also allows them to play on a map they are more comfortable on.
