As mentioned by Cybernetic, wowmaps "Draw all Quest-Icons" option puts all quest on map. Unfortunately, addon doesn't know about public quests, so as soon as public quest is unlocked, it puts ! on NPC. Have to do public quest to get rid of that ! marker.
Not ideal workaround, but a workaround.

Oh, and people who have more than 3 classes are clinically insane.
