Stick It To 'Em!

I couldn't mount any of the gryphons at the end (clicking them did nothing), so I had to ride to Arom's Stand manually. I was still able to turn in the quest.

The gryphons fix themselves exactly 5 minutes after you ask Inquisitor Cleardawn to send the signal. At the 5 minute mark, gryphons 2, 3, and 4 will phase, and 2 and 4 will become non-interactable. You can tell they are "ready" when only gryphon 3 is interactable.

I've tested this quest like 20 times tonight and I personally found no correlation with anything else I tested.

Things I tried that had no effect:
- reloading, relogging, and relaunching WoW
- using the Throw Liquid Fire ability before clicking a gryphon and before talking to Inquisitor Cleardawn, thrown both away from NPCs/gryphons and at them (via Ishmalara in eadierlam421's comment)
- killing the exact amount of Witch Forces needed and no more
- killing the last required Witch Forces within the Crimsonwood Demolisher auto-exit area at the northwestern ridge
- triggering the auto-exit while the Demolisher was in combat, not in combat, at full health, and not at full health
- using only the Demolisher's Slam ability, ignoring Stomp and Speed Up
- manually exiting the Demolisher before entering the auto-exit area
- clicking gryphon 1 while it was still interactable (this is the only gryphon that phases correctly, and becomes non-interactable once it lands)
- mounting and dismounting while gryphons were bugged
- talking to Inquisitor Cleardawn, Warren Ashton, and Marten Webb between clicking the gryphons
- clicking all four gryphons multiple times
- clicking one gryphon repeatedly (I gave up after 60 failed clicks)
- clicking none of the gryphons (still phase automatically after 5 minutes)

On an unrelated note, be careful abandoning and redoing Stick It To 'Em! after the gryphons have fixed themselves. If you do so without taking the debugged gryphon to Arom's Stand, you're likely to get disconnected a few times when you try to take control of the Crimsonwood Demolisher. Abandoning and redoing Stick It To 'Em! while the gryphons are still bugged, or after taking the fixed gryphon to Arom's Stand, will avoid this.

This was my first time doing this quest, but it's apparently such a rampant bug that I'm surprised it hasn't been fixed yet...

Edit: To add further details, I was in Warmode, and as I recall there was no assault active in Drustvar at the time.

WTF! Stick It To 'Em! AFTER you kill the required number of mobs, they take your ability to defend, kill the mobs away from you and you’re left with a 10 second RUN through ALL of these mobs. Then you’re told, go northwest. Really? Northwest, um any place northwest in particular or just northwest? Of course, the mobs can hit and kill the vehicle you’re in and suddenly you find yourself in the middle of hundreds (it seems) of mobs, three of which are elites that wasn’t that easy to kill during the quest chain when all you had to kill was them.

So, unless you’ve done this before and KNOW this is going to happen, station yourself at the turn in point before finishing your quota, or plan to die. Of course, that presupposes you know where the turn in point is in the first place. which, by the way, is located at /way 19.33 50.81. And a good place to station the vehicle is /way 19.73 52.37 (just down the hill but I don't think that large thing will make it up the hill and that's a short run. Rock throwing distance.

I’ve said it before, I’ll keep saying it. Blizzard programmers, regardless of what they say, screw with the players. Especially the casual player who doesn’t care to be top notched geared, or ran through these things during Alpha and Beta so they KNOW what’s going to happen.

Seriously, why take away our ability to kill the mobs while in the vehicle before we’re ready to exit the vehicle? One reason, screw with the players. No other reason makes any kind of logical sense. Honing our ability to run away from a ton of mobs?
