With Bora 'Yellowstar' Kim remaining the only remaining original Fnatic member during their LCS-era, the team has locked in their members for all positions.

With Enrique 'Xpeke' Martinez having left to form team Origen and the departure of Lauri 'Cyanide' Happonen, Martin 'Rekkles' Larsson, and Paul 'sOAZ' Boyer, Yellowstar cementz himself as the backbone and remaining support of the team. After his departure, sOAZ made a statement:

I have been able to experience so many good memories, some of the best in my entire life, with Fnatic. I want to thank everyone that worked with us and all the people that I have played with, it was a hard decision to make but together we felt it was time for me and Fnatic to part ways. 

I have been playing league for a really long time but this is not the end for me. I want to wish the best to everyone in Fnatic. I’m looking forward to seeing the new guys play in LCS and cheer for my boy Yellowstar. Lastly I would like to thanks all the fans that have been supporting us for the past few years, it truly means a lot to me.

The new Fnatic line-up is made of Two Korean players and three European players.  The line-up is as follows:

SeungHoon 'Huni' Heo - Top
Kim 'Reignover' Ul-jin - Jungle
Fabian 'Febiven' Diepstraten - Mid (formerly H2K)
Pierre 'Steelback' Medjaldi - ADC
Bora 'YellowStar' Kim - Support
