ah ok wrathion was in mop. Maybe thats the reason anduin punched him in bfa.
What i dont understand with this fomo stuff. They proved with the new magetower, that it is possible to re-release something and keep it a challenge for the players. But why remove a questline 
. Maybe the new blizzard is willing to patch those quests back in to the game 
. Sad thing is that a couple of players would be mad then, because they are something special.
