Items Just Not Worth The Time Spent Camping

[Gumbo]

I thought of this topic when I was in hour five of waiting for Hadden to spawn in Qeynos Hills and hoping it wouldn't all be a waste of time... My reward, a fishing pole and 1 platinum. Hadden, who has the Fishbone Earring only spawn everything 6 hours and if not killed within 20 minutes, despawns. But if you do fight him when he spawns, there is the chance he won't even have the Fishbone Earring. I wasted six hours for nothing... I could made 3K and just bought the damn item from someone who was lucky enough to waste all their time and just happen to get it.

What other items besides the Fishbone Earring is just not worth getting because of the wasted time and very slim chances of the item dropping?

I was thinking of the Goblin Gazughi Ring. Great item to use when animal charming but I did all my levels without it and had no problems with animal charming. I might get it if I decide to hit the Polar Bear caves in Permafrost but I can always buy it now.
