Brand Extension

[V]

So, I'm on wwe.com and realizing there's no superstar page for Raw and/or Smackdown stars

after some google searching, I realize the brand extension has been over since August 2011?

Are Raw and Smackdown fully integrated now? If so, I have a few questions

-why did this happen? (i mean insider details, did vince finally realize the brand extension was a horrible idea?)
-has WWE been better since?
-do a lot of wrestelrs still only appear once a week, or is it pretty consistent they're on both?
-why are there still two titles? is one considered "better"? has there been any attempts to unify or have a title vs title match?

this actually may get me back into wrestling again.. it's one of the reasons I lost interest
