I was wondering on where the mount could drop if it was in an instance. Since there is a pet to, it would make sense if the pet was for the 10 man version and the mount for 25.
But where would it make sense, as algalon is old content, and uldum only has 5 man instances (which also wont come out for ages).
It would also need to be of a similar difficulty to lich king 25heroic.
So considering all the raids that we have, and also including ruby sanctum.
There seems to be in my opinion only one place.
Vault. Now I know what your thinking, none of the bosses on there own even compare to even deathwhisper.
But what if it was all 4 together?
Now I dont want this to just be a speculation post (which tbh it is.) But I also want to generate a conversation on whether these 4 bosses could be killed together. Would the difficulty match some of the higher lich king hard modes?
