I disagree. I like that the tag titles are unified but the rest really aren't that overbearing since they are on specific shows. I cannot agree with the thought of merging the major titles but I would agree with bringing back a lower level title for ECW, I know the show is short but when you only have the ECW title it feels like the majority of the roster, those not fueding for the title, aren't really doing much more than trying to escape ECW, which depreciates it.
Ending the roster split at this point wouldn't really serve any purpose. The roster has grown to a huge number - Raw has 35 Superstars, Smackdown has 35, and ECW has 22 (pretty sure). For those not wanting to do the math that's a total of 92 wrestlers, quite a few wrestlers that wouldn't benefit from this. They have just 34 more wrestlers/others than TNA and 3 times as much tv air time.
Besides we just have to face it, not only is ECW not the old ECW but Raw and Smackdown are not our old Raw and Smackdown, respectively. The product has changed too much and gone too far to go back. Raw is no longer a War Zone and Smackdown is no longer the home of good ol' poontang pie. To end the roster split now would make all the progress of the last 8 or 9 years pointless. Fake competition has entered the WWE now and it is here to stay, we should think of ways to improve it not dismantle it; our favorites are becoming legends and that's great, except that legend means you're getting old and sadly won't be around forever, it's time to start looking to the future and build, as I'm sure WWE is looking to do.
As for bringing back sole-show ppvs I would terribly disagree. I remember the ppvs following the roster split and they weren't that great usually. The problems are that a lot of the time it felt like they were filling the ppvs with boring matches also what happens when they stack one show with better talent or matches? The ppv sales start to fluctuate more because some people around the world don't get all of the shows. I assume someone lacking MyNetworkTV access isn't going to want to buy most Smackdown ppvs because they won't be as involved. Also that means shows go sometimes months without a major match or title change, since title changes on weekly shows is rare. Let's try to remember that they brought back the World Title for a reason.
