Scarab Lord chain is the most interesting quest chain and the most annoying are Hemet Nesingwary's hunting quests. Though in WotLK we can see some progress in them.
Those mechanical chicken quests, when I'm too low level to do the quests the beacon just keep on dropping, and when I actually want to do the quests, I can't get one.
Back in the day, the hardest Hunter quest was easily this one: [Only registered and activated users can see links. ]
You wernt even allowed to use your pet to kill the 4 elite mobs so you really needed to know your class. Plus if other people helped, the mobs would evade and you would fail the quest.
Not to mention you need Mature Black Dragon Sinew which drops from Onyxia plus you also need an item from Molten Core, but i forget what it is.
It's still quite possibly the hardest quest a hunter will ever do, even though you can easily get the items from Onyxia and Molton Core now.
Hardest quest, I agree.
Most annoying? Hell no!
Finally a quest that is a challenge rather than killing 5 easy dogs with 2 hands on your back.
I really liked this quest a lot and I happily died a few times. I didn't even die on all others since it's not too hard. If you know what to do and use your kiting abilities it's actually a lot of fun to do.
It does get quite frustrating when some noob comes along and attacks the quest guy or you get ganked by the other faction while doing so. Shit happens, get over it.
Was my most fun quest actually.
2nd most fun quest would be racing for the dragonmaw. Also a quest with a challenge
Most annoying quest definitely Onyxia attunement. Only the way from OG --> UC --> Badlands was ****ing annoying each time. Then the hours spent to get a group to some shithole like LBRS. Glad that attunement is gone now
Its a shame that you can no longer get Scarab Lord title I always dreamed on one day starting/moving to a new server and getting it with some buddies.
Most annoying, probs the dragonmaw quest. It wasn't hard and was pretty fun, till the last guy... tried it a few times, gave up and never came back >.<
balance of light and shadow. the priest one you had to wait on the eye drop in the core, save all the people from the skeletons, and find a grp willing to kill lord kazzak.
But evryone that has ever created a Troll or a Orc knows the pain in this quest
I am talking about the most annoying quest ingame...
Namely "A solvent Spirit"[Only registered and activated users can see links. ]
I dont remember how many times i have cursed this quest !
lol i remember LONG ago back in the early days of vanilla , when this item was on the ah for hundreds of gold and , the top pvp'ers were making alts to 10 just for this item , cuz of it's use in bg's
