We saw Aspas, Cned, and one Jett guy from Levithan; they all play Jett in every match, and all of these guys and their team dominated.
imo The scene would be different if C9 gave Yay Jett, and the same for sentinels , because we know these players will get an average of 15 kills, and you want them to play in their comfort zone, where they will either make space or get kills.
Dropping Yay will be the great mistake. C9 will suffer mark my words.
