@Vall Why would anyone compare it to Xenoverse or.. League? It's obvious that's not going to happen, since they're not the same type of game. I've played plenty of different MMORPG's and people who also have will compare it to those, and even more to the original DBO, which even had some annoying areas.
Most MMO's, while there's grinding involved, there isn't pure mob-grinding every single level just to unlock some more quests in almost all of them; that would be ridiculous. Then as you get higher and it scales up even more, people will just not feel like it's worth it, especially with the fact that there are games like these out there with much better engines. In fact, comparisons won't even be needed for anyone to reach this conclusion. This just won't apply to die-hard fans, though.
There's making things harder and more satisfying to achieve, which I enjoy, and then there's making them unnecessarily dragged out and time-wasting. This falls into the latter category.
Also, you say you don't want to see those daily quests again, but what he's saying is that doing those is exactly the same effect we'll get from this huge change in the exp curve.
Edit: If running out of quests only happened every 30 levels or so, and then dungeons gave a much larger amount of experience (much like a certain mmo I know), then maybe most would be fine with it.
