I would agree on what a useful call needs to contain before deciding who should speak most often. A location, an observed action, and your own intention can be enough; a running commentary on another player’s decisions usually creates more noise. Try asking everyone to stop giving instructions once they have shared the information the surviving player needs. After the match, discuss one specific moment rather than judging somebody’s entire performance. You can keep the cosmetic conversations for the lobby. That gives both topics a place without turning a casual evening into a lecture or making one person responsible for every decision.
