I am glad if the brand extension has truly ended.
I never liked the brand extension from day one. It was insulting the intelligence of the fans, by pretending that they were two seperate brands competing- like how would we know when one brand finally won. In the Monday Night Wars, WWE was the ultimate winner, because WCW ended. But if either the Raw brand or Smackdown brand was beaten by the other show, it's not like it would go out of business. It doesn't matter if Raw or Smackdown won the brand war, because it is all WWE anyway, so it wasn't a real "war" anyway.
I also didn't like that they were restricted to certain feuds, and couldn't do feuds because two superstars were on different brands. I like to think that "any" top-liner can challenge the champion for the title, not just some. It just makes sense that if everyone is together, there are more opponents to fight, thus fresher feuds. Instead of seeing two people fight for the 1,000, 000 th time, you can throw a lot more opponents at the champion.
Also, it is bad business by WWE to have a brand extension. If someone likes a particular superstar, they would just watch the show they were on. It would be better to have the same superstar on BOTH shows, so that the fan can watch their fave on Raw and SD, increasing the audience for both shows.
Some people say that it would hold back mid-carders. But I think that "Raw" and "Smackdown" should "earn" their spot on the show. I think that you have the superstars from both brands, who have a major feud going, on the shows, and have the rest be on "Superstars" for the time being. If a mid-carder or cruiserweight performs well enough, or they are in a major storyline, they can be "promoted" to the top shows. It will be something for them to strive for, and some mid-carders will have to lift their game, to earn a promotion to the "big leagues".
Also, with the WWE-World Title problem, I think that "Night Of Champions" is perfect to solve this. I would change the main event, from Cena-Del Rio, to Orton-Del Rio. Or, more specifically, WWE Champion Alberto Del Rio versus World Champion Randy Orton, in a title unification match. I think that they missed an opportunity last month, that instead of having two WWE Champions fighting in a unification bout, they should ahve announced the night after MITB, that Christian is the sole WWE World Champion. If Punk came back, have Punk vs Christian at "Summerslam" to unify the title. But they could unify them at "Night Of Champions" instead.
I would also have another match at "Night Of Champions" be the IC title vs the U.S. Title, or maybe have both belts, and use the U.S. Title like they did the European Title.
