I just leveled a hunter to 110 since 7.3.5, taking it slow. From my experience it goes faster then before.
The only thing that is slower is killing mobs/bosses. Been queue for dungeon whole time while doing quests in between.
The best part is that you choose a zone you want to experience and play trough that story full.
I already know the next zones ill be exploring on new toons in the future. I love the change.
