Ofc it won’t happen so no amgery please, just a ‘what if’ post here. Since we already have area level scaling to our character imagine if Nightmare and Hell modes are gone and we end up in those random maps endgame after beating Normal.
Would it be just D3 rifts or some more complex system? Quest rewards would have to be given some other way. Sorc teleport would not be that op anymore and no more cheesy Andy/Meph etc farming. Skipping mobs like immunes would be pointless, characters would have to be able to deal with them or no progress. Could be cool fresh experience for leveling without replaying same story again.
