You all know that Engineers can warp team members to his location, but I want to see a new addition to this. What about making a tradeskill item that makes it possible for the Engineer to warp himself to the location of the trackeritem he have dropped off somewhere (he's the master of technology?)
He can drop the trackeritem in front of the mission before the teams starts and when they are finnished he can warp himself to the mission entrance or somewhere else (but only to the trackeritem). When he have warped himself he can start to warp the others if they want to.
You will use the current Beacon Warp, but when you are trying to warp yourself you will be warped to the trackeritem instead of your current spot.
To prevent exploits the trackeritem will dissapear when the Engineer dies.
