The WWE needs to unify the rosters back together in general, and go back to the old way they did things and have the entire roster on BOTH SHOWS. The only reason they split the rosters between RAW and Smackdown was because of the acquisition of the WCW and ECW wrestlers in the first place, but a majority of those guys they acquired all either went the indy route or are in TNA.
I'm fine if they unify the titles back together, but I hope their next step is to reunify the WWE roster. Since TNA is starting to take some established WWE, WCW, and ECW talent onto their roster anyway, the WWE roster seems to be back to the reasonable enough size for it to be reunified in order for the entire roster of talent to appear on BOTH SHOWS.
I mean, they've been doing a lot of "interbrand" storylines in the past couple of years despite having two separate rosters. It's eventually gonna have to come back to putting the WWE roster back together as one united unit, it's not like they have issues of an overcrowding roster since they're cutting away some of their established talent left & right to make way for the young breed.
Although, I do agree with what Wing Saber said about keeping the Intercontinental Title and US Title separate. Despite having the same meaning, those two titles seem to be unique by their reputations anyway dating back to the old WWF and WCW. ****, we don't even have the Euro Title anymore since it was unified with the Intercontinental Title........so we might as well keep the US Title around as the substitute for the Euro Title, despite not being "Euro."
