I am surprised at you Ned Stark, you of all people should know that armour is not heavy at all. A late medieval tournament armour might be, but a true combat armour dont hinder the wearer much at all (and after all the individuals that wore them trained in them constantly) :)
And I agree that if u want those heads rolling, try to maximize the chances with the right equipment/traits etc.
Personally I dont mind the wiedergangers returning from the dead, its the flavour of playing against them, however the suggestion of being able to interact with fallen enemies is a good one, though not something i believe the developers really need to focus on.
