even if the "helper" is relatively crap? perhaps if 1 noble can only get 1 helper? both have to be stationary, at least 1 has to spend hours.
perhaps if the one being helped has no healer he doesn't get helped even?
i mean.. imagine 1 normal healer heals like 10 points.. the helper heals 1 (or however the whole healing thing works) it'll be fairly pointless. (which of course means a bit of a waste of time coding it XD)
