Yes, we'll have to wait and see. They said leveling up would be easier. Also there will be very difficult crafts so that people that get the best gear and melds have some satisfaction.
I hope the cry babies don't make us get very difficult crafts (for very desirable items) on which we lose extra expensive mats a few times until we succeed because of RNG. People complained about raids being too easy, then a difficult raid comes, then a ton of raiders quit because it is too difficult for them. We'll see where the difficulty is in the new difficult to craft items to come.

The fact that there are less ability slots needed on the bar is a good thing, there were too many. There is a total change, we'll have to learn how to use abilities again and adapt to the new situation.
