Look I dont mean by "Dropping" Boaster by any chance. He is known to be a great IGL since the start of the game and he is very smart in terms of strategic ideas and plans.
But he gotta fix something in his gameplay. He only outaimed Bilibili (Which were looking rough) in all of champions teams that they played against.
I like a comment I saw on a chinese website: "When u look at boasters POV u can see him dragging his crosshair onto ppls heads but he just doesnt have that kind of reaction time to shoot infront his enemy because he is in his 30s"
