I remember an incident in Red Orchestra where we were on a tank map. A teammate hopped in a tank. So, I did too. He jumped out of the tank and into another; so I joined. He jumped out and started shooting at me, basically insisting I get my own tank. Apparently, his level of tactical sense and reflexes in a tank vastly outweighed the value of having a second player in the gunner’s seat; even though the game was realistically meant to depict tank crews cooperating.

It's a common issue with lots of team play games. The other player decided that it was better to have two people operating separate mortars than to have one of them provide small arms cover on the flanks of the tank.

Helldivers 2 has a similar problem where some players can help other players reload their larger weapons at a much faster rate than typically; however the player base decided that it's better to fan out and each operate the weapon solo because shots do not need to be made so rapidly and clumping together increases the odds both players die.
