Leftovers' Revenge

Blizzard, please make this achievement more accessible. At the moment, it is practically impossible to obtain. I don’t want to spend hours of my time outside the game searching for other people who want to complete it. The achievement itself is not difficult, but the requirement to coordinate 20 players in an old expansion makes it extremely hard to get. Not to mention that the rare mob gets one-shot, and not all of those 15 players even receive the achievement.

For completionists:

It's very early in the expansion and this is cute and easy, BUT! remember that once the expansion is over or perhaps towards it's end it will be increasingly difficult to summon this and you'll need a large group of people to summon.

As far as I am aware, currently this is not possible to achieve solo.

EDIT!: As of the end of 10.1.7 the only suitable time to do this is during Aiding the Accord: A Feast For All

Even in a raid group of 20 this is basically impossible with how sharding currently works
