That horse you're on is pretty high, perhaps coming down might make you seem less sarcastic. Even me, someone who finds zero difficulty with dungeons, can agree to at least extend an olive branch and give an easier mode for dungeons (if only for the story). It would come at a price (your rewards, or much less of them). If people do not wish to use the tools given to them (npcs) or cannot do it even with them then a line has to be drawn somewhere. If you give even the skilled players a spammable rewarding mode then of course they'd use it.

Making everything only difficult for the least skilled makes for a very boring combat game for everyone else in PvE.
