We've known for a long time that Laz can handle Sentinel, Initiator, and sub-Controller roles at a high level, while Dep can excel as Duelist, Initiator, and sub-Controller.
Despite this, they stubbornly clung to hirororn's Initiator role for a year, even though he couldn't play it properly.
The current composition, which they probably haven't practiced much, is far stronger.
I don't know who decides the team composition, but if they had started with these roles from the beginning, the results might have been different.
