As a champions contender? I think they tend to choke and lose when it's on an important game and basically some teams looks better than them (PRX, FPX, and perhaps Optic)
Of course. They were the first team to play against PRX so they didn't have much footage + PRX style is really different to what they are used to. Like do you think FPX would have won so dominantly against them on Bind if it wasn't for Fnatic vs PRX? And Fnatic still made both maps close while also losing majority of the pistol rounds.
And Leviatan in other hand isn't a bad team and also play pretty different to your typical EMEA team.
My overall take away of Fnatic is that they are just bad at adapting to different styles and their individual players especially Derke and Mistic were not on their peak form. So in that sense it doesn't favor them heading into Champions, because now there's even more teams that play non typical EMEA styles. But I do believe their group should favor them because it will be more comfortable for them. Also if they still have Breeze as their perma ban and aren't good on Pearl then it will be a problem. I do believe in their ability to learning new maps quick tho.
