It is very unfortunate, to be trying to play tactically on a server in a cooperative mode, and for some players to enter, that the only thing they are looking for is to kill and destroy quickly.
I propose to offer the option to the administrators of the servers, to define a time between objective and objective, to avoid those corridors.
During that time, waves of attacks would occur until consumed.
This could be done by restricting the capture area, in a larger radius, perhaps up to half the space between the targets, and that radius would be progressively reduced, as the indicated time decreases.
