In essence when attempting to complete a VIP rescue mission at higher level even if you sprint to the vault/secure room in which the vip is held you get there about 10 sec before they destroy the door at that point all the mobs you pulled along the way catch up to you and slaughter the VIP while your killing the masses. The vip is not very smart either and will stand in enemy's AOE effects until it dies which if often as you will pull elite and commander bosses along the way to rescue VIP. 

Everysingle mission to rescue vip at the higher level (over 60) has ended in this scenario i despise VIP missions and avoid as much as possible as I know it's a straight failure whatever it is . Can something please be done about this. ?? EG have the door timer start only when you're in  close viscinity of the vip or at least have the way to the vip be clear.
