I understand the reality concept of not being able to attack through a closed door, but when engaging a mob and then having the door close and not being able to cast at it anymore untill the door is reopened is life threatening to us nano techs to say the least. Why cant something be built in to have any door in a mission that the player has allready opened remain open. Also the range on nanos being modified to 40m is understandable for PvP, but in missions this is also pretty deadly as well, considering it seems that most mobs have at least that kind of range or very close to it, and sadly enough us nano techs are not quite as hearty as our soldier and enforcer counterparts.
