Yes and No
If I understand the question correctly, you suggest that that Raw and SD should combine rosters
Recombining the rosters would cause overcrowding in my opinion because a good portion of the rosters would be buried in the process due to this. You have a decent set of top card and mid card on SD and RAW but when you look at ECW they really only have RVD, SABU, Sandman, CM Punk and Big Show to showcase the rest well they dont matter at all to WWE/ECW product and it shows. A 2 hour ECW show would only work provided they stop burying Balls Mahoney, Dreamer, and the rest of the ECW originals, get fucking Striker and Rene Dupree back on WWE shows and bring in some old school ECW favs. Also they need more extreme rules matches otherwise just get rid of the damned thing because this isn't ECW at all!
Now back to combining RAW and SD. It would work in the sense that you would have some great matches and feuds that haven't been done yet but again I worry that there will be a lot of guys that wont get any time at all and what WWE needs is to focus on some of the newer talent rather than just continuously rehashing the same old tired storylines and feuds every week.
Should the WWE reduce the number of ppvs a year to one every 3 months or 4 months. Or Should they go back to just the big ones such as Summerslam, Survivor Series, Royal Rumble and Wrestlemania?
