I was just thinking to propose this suggestion..how cool it would be if the leader is allowed to cancel the task reservations done by anyone in the co-op...
I know there is an option to restrict reservations partially and completely but sometimes when people hold up tasks for too long it just becomes pain for other players..it would be great for teams that have reservation time policy for example reservation allowed only for 2 hours..If leader is allowed to cancel the player reservation 'n' number of times it will make things easier for the whole co-op.
