Correction: 50 was the max character level, 100 was adding in the paragon levels after that. The process was longer due to horrible itemization, less multipliers, and overall a lack of damage from all classes.
This is what I mean by you asking they do a complete 180 from where the game is now. You want challenge in the early levels because there is no challenge. They reserve that challenge for the endgame, this is what they’ve stated.
So now 60 is the max character level, with 300 being the max paragon level. Your example is actually worse in this case because you’ve already hit max character level before completing the campaign. It would be the equivalent of being level 60 with 30+ paragon points.
People asked for more endgame content, but also to be able to reach it faster at the same time, this is the trade off. Now the other game does things differently, focusing more on the campaign with a little bit of endgame, so far anyway.
Again I’m not disagreeing with your suggestion, I’m just giving the reasons why I feel they wouldn’t change it back to what it was, based on what they’ve said, and the actions they’ve taken since they started to move in the direction stated.
