Some suggestions

-Might have scrolled past someone making this point allready-

Aside from issues with trolls/unintentional trolls I have had numerous situations as both gunner and engineer where allowing the gunner to take the gun without delay for voice or text chat to arrive and be understood would have been advantageous ex allowing the gunner on a fish to take the side gun when arcs are lost more than briefly after having the engineer start shooting it. As engineer it would be good to be able to take any gun and start it firing without forcing the gunner to inform you when he returns to it.

Nobody made that point Daft Loon, and it's the only useful thing from gunner priority I could think of. It's a minor boost to gunners in limited situations. Everyone's focused on kicking new crew off the goldfish gun. There's no substitute for communication.
