[dev1004] Upon meeting the objectives of a main scenario or class quest, an exclamation point (!) icon will appear over the NPC offering the quest. An exclamation point icon will also appear over the heads of NPCs with whom a player must speak to advance a quest.

WHY? I was glad the exclamation points where on the map/mini map only, why over the heads? If you want to make it easier why not just have them all visible on the city map??? :S
