So I never got around to actually getting the achievement when you could all sorts of tricks and mobs to get the achievement with, but now that our server unlocked the final stage of the Isle, everything I've tried doesn't seem to work.
No more troll canoes are spawning.
No riders over Violet Rise flying over.
The troll pat around the center is gone. I waited for a half an hour with no avail.
Can't find a Mogu, Troll, or Saurok that works.
The Mighty Devilsaur doesn't work.
The random wildlife doesn't work (Though I knew this, but I figure I'd try again anyways).
So what the hell works now, or is this doomed to be a PvP achievement?
