The Japanese casters refers to Laz as the leader/captain while casting or whenever they interview him. On ZETA's 2023 roster announcement, Laz is written to be the leader. Even Laz calls himself the leader of the team.
But on the english broadcast, the desk says that the IGL is crow. And also Laz talked on stream after Champs about how you can't see an IGL's impact through the stats, which I assume was to defend crow's poor performance. I'm not the most fluent in Japanese so maybe I misunderstood.
So is Laz or crow the IGL? Is Laz like the leader outside of the game and makes secondary calls? Or is he actually the IGL?
