It sometimes feels as though this game is filled with very tedious NPC's who are desperate to give you their quest. Sometimes they even come at you several times from several directions as you try to move through the landscape on your way to somewhere else. Sometimes they are really quite rude, calling you "initiate" or "vestige" or making other rather offensive presumptions about you, or are the opposite and go on about you being the chosen one, which is equally tedious to some people (including me). Others are pathetic and clutch their elbow, and then you feel bad for not taking the quest.
My new least favourite is Anais Davaux. She is at least courteous, and there is only one of her, but she is placed right where I go to do provisioning. One day I took her quest just to shut her up, which is why we need 50 quests in our quest journal. However, going through her admittedly charming dialogue I found out the quest was from Abnur Tharn, so I obviously didn't do it. Yet it turned out, this toon then got the big cat Companion, Zerith-var. Unfortunately this new breed of Companions wants you to do obscure questlines in order to get the dailies that boost their companionship. But as I had the quest on my quest log, I could not find it in the game.
So, who is your least-favourite quest-giver?
