Well from this, other than Azerite being present there, there doesn't seem to be a reason why adventurers are sent back to Kezan.
If they made the entire island a dungeon with multiple wings leading up to a lore relevant boss then it would be cool. At the moment, this just seems like a way for blizzard to get some goblin points and say "hey, we went back to kezan, now shut up already!"
