I feel like there is a lot of overreaction going on here. Yes, the recruiting has fundamentally changed but the majority of the 2.0 style had been around since the game's inception. I feel that no matter what changes were made, people would complain because they were so drastic, and it seems too soon for people to be making such definitive statements - It takes time to get used to anything that is drastically changed. Everyone had their methods and tricks for 2.0, and if you play and give it time, I'm sure we'll all develop new methods and tricks for 3.0.
Also, it isn't like Hoops Dynasty was thriving with users in 2.0. While we have/had a core group of veterans who intend(ed) to play the game as long as it exists, there was no real growth, and that core group is smaller than a lot of people believe. Season after season people would drop off piece by piece and it was a matter of time until the worlds were near baron under 2.0.
The 3.0 changes at least give WIS a chance to bring in a new user base that can fill up worlds and give us more users, but it's up to them to deliver on their marketing end.
