This is one humorously heated and circular thread. Why's Ziggler getting a World Heavyweight Championship opportunity before Kofi Kingston at The Royal Rumble? It's pretty simple.
The World Heavyweight Champion, Edge, is a face.
Kofi Kingston is a face.
Dolph Ziggler is a heel.
Dolph Ziggler is managed/kayfabe-screwed by Vickie Guerrero.
Vickie Guerrero is Edge's ex.
They're pushing Dolph at the moment, but it's a test run.
As a general rule, you don't want your big momentous first-time-ever world championship shot to be at The Royal Rumble, if you're looking to win.
The storyline is there, it's an easy job for creative to piece it together. Just watch, the promos will mostly be Vickie vs. Edge, with Ziggler as the former's proxy.
Kofi needs to drop the Intercontinental Championship to Jack Swagger in one of the first-hour matches at The Royal Rumble, then win the 'Rumble match. Kofi should eliminate Alberto Del Rio, who's made it his quest to win the thing. Del Rio takes the WHC from Edge when Christian turns on Edge at Elimination Chamber ala Matt/Jeff 'Rumble '09. Christian/Edge, non-title (they could redo it next year with Christian as a face for the title in Toronto), Kofi/ADR for the WHC, if they really want to make seriously big stars out of these guys, then in at least a couple of instances they need to go all the way. The Money in the Bank institution, with no less than three briefcases a year, is a monster that Luger-izes first-time champions--Jack Swagger has Mt. Everest to climb if he wants the fans to take him serious at the top of the card and as a champion. It's time to do it the right way again.
Then they can turn Dolph face against Vickie, who puts a bounty on him in the Wrestlemania MITB match so the odds are against him. Anyone who takes him out earns perks and privileges from the #2 force on Smackdown, so you've got numerous heels looking for that as gravy on the briefcase mashed potatoes along the way.
Also, as an aside, comparing Ziggler and Kofi in-ring against each other is highly difficult. You're talking about a kinetic, energetic babyface who utilizes martial arts and Capoeira within his frame of reference, frequently flying off the top turnbuckle and going for big spots to hit within the ebb and flow of the story of each match, and in the other case you have a guy with one of the most expansive signature move-sets in WWE who incorporates old-school grappling psychology and indy-influenced, pretty awesome chain-wrestling ability (one reason he could hang so brilliantly with Danielson back at Bragging Rights). One guy's a classic babyface, the other guy's a classic heel. Each guy incorporates mannerisms, movements, timing tricks, episodic shows specifically for the crowd between spots, and making the spots as fluid and organically at one with the overall story of the match entire. You can see it in the Kofi/Ziggler matches. They complement each other very well. Don't see how Kofi can be derided or dismissed as a "spot monkey," either, seeing as he's had an assortment of very fine matches with a great variety of opponents in the past calendar year, ranging from Sheamus to Drew McIntyre to Dolph Ziggler to Jack Swagger and several others, all of whom present at least considerably distinguishing characteristics from one another, and the matches have all been substantially different from one another within each series of bouts with a given opponent. For instance, each one of Kofi's matches with Swagger has told a remarkably different story from the others previous. On some occasions, Swagger is fiercely dominant; on others, the battle is more 50/50, and on still one or two others, Kofi is the more aggressive party, but they all tell very intricate and complex stories, and require the old cliche of two to tango rather than one of the workers being a "spot monkey," which would naturally and consequently limit the luster of the matches.
