Leveling was fun. It made wow feel like an rpg again.
The streamlined difficulty was also a plus for me. I liked how solo leveling in Wetlands was just as difficult as running scholo.
What made me quit was that at end game it required extended hours to get something done in a single sit down session like some of the end game dungeons. By the time you log in and assemble a group, navigate to the dungeon, then actually run it, it takes up a few hours. So if I didn’t find a group within the first 20 minutes of logging in, I basically had to halt my character progression.
I ended up leveling two characters to 60 in prep of TBC.
