If you want to give a certain character more TV time, have them win a midcard title. They will get over quicker and if its a failed experiment, WWE can simply take the title off them. If they are so into the idea of building stars, this would be a nice little ace up their sleeve so to speak in building process.
What you've said here is not a means of making the IC/US/Divas/Women's title any more 'legitimate', you've actually just explained the whole purpose of having those title belts. To help promote certain talent.
Mid card belts are there to make the talent themselves seem more legitimate, so that if Raw was ME'd by HHH vs JoMo, then people wouldn't immediately say 'WTF?' because JoMo's held just about every mid-card title, so by now, he should be stepping up to the ME anyway (ya know, if wrestling were a real sport).
The reason that the mid card titles don't seem important to some fans, is because the wrestler themselves act as if they don't actually give a shit about them either. Back in the day, less than 10 years ago, guys like Jeff Jarrett and D'lo Brown used to talk about being the IC/European champions as if they were the only belts that mattered to them.
Crash Holly was so proud of being the Hardcore Champion, that he invited all challengers to take him on 24/7, and he didn't show any interest in any other belt.
Guys like Chavo and Rey and obscure cruiserweights like Tajiri and Jerry Lynn that popped up in the 'E', were
only interested in the cruiserweight title.
How often did you see Bubba Ray Dudley or Headbanger Trasher waltz into Vince's office demanding a WWE title match? Never, because they were strictly tag team guys, and they only cared about tag team gold.
10 years later, and it seems as though in the mid-card, no one but the tag champions gives a shit about their own titles. Miz has shown more interest in being the US champion than anyone else has in the last year.... mainly because he's the only one to be given a mic, and when do you ever hear any of the Divas actually talk about striving to become the champion? Never, because they're too busy playing out typical stereotypes about females instead of focusing on getting us interested in the 'wrestling' portion of world
wrestling entertainment.
Just a promo every now and then with
challengers instead of the champions, would probably do wonders for the mid-card titles and actually remind the audience that there is a point to them being there.
I see Miz talking a lot about being US champ, and then suddenly some GM will come in and say, 'ok, you're defending the belt against MVP........... (again!)' and then do they bother to go talk to MVP? A man who's had like 5 or 6 US title shots and lost them all? Don't you think he may be fired up or have loads of passion about possibly becoming the US champion again? Well, we'll never know because they never fuckin' ask do they?
The champions are being made to make the belts look important when it should be the other way round. Simply having talent show interest about having any sort of title reign will help the image of the mid-card belts. Having the champions try to convince us that there is in fact a division that cares out there in the back somewhere, obviously doesn't.
