This is a huge topic, and something that has to be discussed. TNA could easily take over WWE in ratings if they did this right, since WWE has seen an all time low in storylines, in fans, and in top wrestlers.
First. John Cena. I will admit, John Cena was the main man back in his Umaga/HBK rivarlies. I loved that Royal Rumble match-up, and always will. But WWE needs to realize that the public knows they are trying to turn Cena into somethings he's not, another Rock or Hogan. They are trying to match the electricity of The Rock with Cena, and it isn't working. WWE needs to have Orton take that title, so this whole boring title reign ends, even though it should have ended at Lashley. Then, put HHH in title contention. HHH is the biggest star on RAW, and the best choice for a title holder, at least until HBK or someone of that caliber arrives.
Secondly, RAW is under-utlizing some of it's best stars such as Shelton Benjamin and Mr. Kennedy. These are guys with the biggest futures. They are young, and they are loved by the crowd(Even Kennedy, a heel at times, a rare thing to find). They need to bump up Mr. Kennedy to the WWE Title area instead of the Intercontinental area, which is a disgrace. Than, brake up The World's Greatest Tag Team, and put Benjamin against Jeff. But in a huge rivalry.
Next. Smackdown! Simply put? Lose The Great Khali. He is a waste of a main event card. Instead, bump up Kane and make him what he should be, World Champ. Him, Batista, Rey, and Undertaker can put the World Title ahead of the WWE title in terms of popularity until Edge returns. Now, Edge. The main guy for Smackdown. Edge has so much potential on Smackdown, he can be the next Heel. He is a popular heel, that is hated so much, but respected all at the same time. Edge gets the crowd into his matchs, promos and speechs more than ANY superstar in this business. Edge has potential to be the best in the business at the moment. He is the boost that Smackdown! needs.
Next, the dreaded Smackdown Tag Division. Deuce and Domino can't do this tag division justice on their own. They need, major competition. Luckily, The Major Brothers, an underutilized tag team, could easily supply the needed boost after MVP and Matt give up the titles. Also, The Highlanders should be plopped down onto Smackdown!, since they aren't being used on RAW, they could make a good impact, both in promos and in the ring, making some better rivalries.
The Women's Title is a huge problem, and should be a universal title. Instead of just RAW, their should be annual matchs that determine the next brand that is up for contention or something. That way talent like Victoria and Michelle McCool, and even the Extreme Expose can get some spotlight. And, would add a rating boost to each brand.
ECW can either be the needed boost to WWE, or, the thing that brings it all crashing down. At this point ECW is in the middle. ECW has top notch wrestlers, and is a great place for beginners to gain experience and learn the tricks of the trade before coming to Smackdown! or RAW to be mid carders or later. But, ECW is supposed to be EXTREME. Not a normal, run down version of RAW and Smackdown with only 1 hour, and only half the superstars. Balls, Big Daddy V, Tommy Dreamer, Stevie Richards, these guys to bring back extreme to ECW and use the ole tables, ladders, chairs on a daily basis. Regular matchs should be the oddity, not extreme rules, which is ruining ECW. I do admit though, without Benoit or RVD, ECW fell. RVD was putting ECW on the map, and the main guy to put it back their, Benoit..well... yea.. ECW needs CM Punk and Morrisson to continue dominating the brand. But Burke, Cor Von, Boogeyman need to put ECW out there, because they are the minor stars of ECW, and need to shine brighter.
Another thing that needs some shaking, OVW and FCW. The two main training places in WWE. As WWE is doing, they need to expand to Canada, UK, Mexico, and further to broaden there prospects and catch the rising stars before someone else does. WWE made a huge mistake when they didn't affiliate with Booker's wrestling fed. It was a needed boost for WWE, and a way to leave on good terms with a legend like Booker, who could end up coming back if WWE got in a slump. But, didn't happen like that.
Some final notes I think would help WWE in all areas... The three big names Y2J, HBK, RVD. Send HBK back to RAW, but not as DX. RAW doesn't need DX, it needs individuals to captivate crowds. Send Y2J to smackdown asap, to help Smackdown in the area they need it most, the mic. And then send RVD back to ECW, because he can add a huge help. He would be like a mentor of the extreme, their goal with benoit, and he could add depth to the roster, in every area; Extreme rules, and the ECW title contention.
