They didn't solve the repetition problem. You're still repeating the same 10 dungeons for 2 years...
The argument of it not being worth it to get stuff at low level because you get something better at high level is exactly equivalent to the same argument but related to lower or higher item levels, but you don't apply it there.
It's a ladder. You climb a few steps at a time - you can't just stand at the top and yell down "ALL THE OTHER STEPS DON'T MATTER". That's nonsense, and obviously so, and yet people are doing it all the time and using it as an excuse to hollow out the vast majority of the game's content.
