I can relate, but for me the annoying bit is seeing those quest markers on the NPCs, not on the mini-map. When I see an NPC with a quest marker over their head, it makes me feel like I should be doing something about it - but in the case of the NPCs in Mor Dhona these quests are for a relic quest that I will frankly never touch again.

I wouldn't mind seeing a toggle that hides repeatable quests, both on the NPCs and on the maps. Probably shouldn't hide markers for quests that you've never done even once, though.
