I was doing the blue daily quest "Battle Trophy" taken from Dorn, in Kamp-Gasphel, Irselnort. One needs to get 25 Thorny collars from Highlanders and 15 Gold-filled Earrings from the Ice Narwhal Boardingers (npcs). The problem is that the chance that Ice Narwhal Boardinger npc will drop 1 Gold-filled Earring is ridiculously small. It takes so long to earn 15 earrings that you will kill estimating 200-300 mobs and spend about an hour doing it (if you are fast and have a minion, then maybe 45 min). I was thinking to put this to the 'bug' section, but I finally decided it is rather a suggestion to increase the drop chance of the earring. This is probably the reason why nobody does this daily quest - it's simply too hard.
