Sometimes I seriously wonder if it's because the USA has better quality pot that people post some of things they do on here, or whether it's just because there are that many 30's in their momma's basement with WAY too much time on their hands.
Whichever it is, brand 'division' is not a problem. What maybe a problem, or is at least inexplicable, is the idea that the brand division means anything. It's not as if SD! concentrates on new talent, light heavyweights, technical wrestling or interesting women's matches, rather than following the same over-written, bad acted, white heavyweight male presentation evident on RAW. I'll admit until recently RAW contained more marquee names (especially faces) than SD and SD perhaps drew more Latino viewers, but the fact that those minor differences have now been evened out further illustrates why the reference to 'brand diversity' is merely demonstrating either a lack of understanding of the product or more likely, the term referenced.
Orton on SD merely takes over from Edge as the the established lead face, with a history of heel turns or tweener behaviour. Regardless of Randall had gone to SD, the lack of back stage support for Christian (understandable from a main event singles perspective) would have meant the WHC run would be short. Had ADR not earned the right to be on RAW taking on SuperCena, then Capt. Charisma wouldn't even had 5 days with the strap.
Whilst unifying the world titles would have had the effect of burying any growth in new talent, keeping the straps separate and likewise JC and RKO, does not guarantee that new talent will be anymore likely to get to the top. The new people to enter the title pictures have seldom been either new people or have it happen on the basis of pure talent. Christian is a vet and dropped the strap through backstage issues not ring work. Mizanin got the strap through bringing in mainstream media attention, something VKM craves to move away from the image of being a wrestling company. Seamus got the nod for being a gym rat and best mates with Levesque (and prospective 'monster heels' are also the most likely to get instant title pushes - a la Paul Wright, Brock Lesnar etc). Barrett appears to have hit a wall for the time being. Thwagger was considered the next Angle but lost back stage support. Punk likewise got pushed, lost support (and he's far more talented than Jack). Morrison and Rhodes have seemed lost for angle - although the latter may have found it. The two most talented ring workers, Danielson and Del Rio, are on the cusp, but there's no guarantee either will take that next step. (I'm discounting Mistico as he can speak english yet so has no chance.)
So, really, until VKM realises that something other selling merchandise, gaining a slot on Leno or being bff's with Levesque matters in a company champ, don't think it matters where Orton, Cena or even Dwayne appear.
