However, while the overall experience is much better, you do run in to the occasional quest that seems to be stubbornly holding out to Blizzard's new, streamlined questing philosophy. Quests that require you to kill ten beasts for a single tooth to drop (why don't they all have teeth?) or run around for an hour (or more) waiting on painfully slow respawns. Recently, while leveling through Outland, I ran into the quest Veil Lithic: Preemptive Strike, which asked me to redeem 3 arakkoa hatchlings and slay 3 arakkoa hatchlings who couldn't be redeemed. It seemed simple enough: Veil Lithic had several nests that spawned eggs. When the eggs spawned, all I had to do was click on them to free the hatchling, which would either fly off or become aggressive. Except after freeing 3 hatchlings, no more clickable eggs appeared. Not in 20 minutes, not in an hour, and not in two -- and though I did manage to collect a lot of arakkoa feathers, the whole thing seemed like a big timesink (several days later, I've still only managed to slay 2 out of 3 hatchlings). At this rate, my attention span is certain to run out before the quest does. (In fact, I'm surprised it's lasted this long.)
And what about you? Have you run into any quests -- now or in the past -- that are the stuff World of Warcraft nightmares are made of?
