The achievement is only counting Full Party (8 Man Groups) Duties anyway.

Don't know about you, but my completed instanced dungeon raid count just hit 500. I'm betting my completed Full Party Duties account for less than 20% of that number.

Why are you upset? The Bear is an okay looking mount, but the White Lion is just a reskinned Chimera with some cosmetic surgery. Neither are really worth putting in the effort to acquire if you ask me.

Dat Bomb Mount is dope though. I am getting that. After I'm done subjecting myself to the torture that is FATE grinding, of course.
