They really need to remove this achevement from the Expansion Features achevement as everything else you can solo but this. You need around 20 people to get it to lengendary and even yes trying to form groups and find Discord groups has not worked. It makes no sense to have it still in when they even made the Mythic Amordrassil raid easier to be able to solo it. Please blizzard remove this ahevemnet list for the mount and housing item. Even tyring to make groups on here is almost impossible.
I’m trying to form a group for this right now… I will make several attempts over this weekend / next week if this one doesn’t workout.
I agree it needs to be removed though… there are several within these meta’s that are impossible / near impossible to solo and trying to form a group for it is pretty much impossible as well.
Its a real bummer because I just have this and one more of the Daycare derby quests and this meta is all wrapped up for me.
