Complete New WWE Title Belts Structure
I see absolutely no need for a women's tag team championship. Maybe in a few years if WWE's interest in tag team wrestling continues and if the Divas continue on their slow but moving progress towards relevance. It's far too soon now. TNA's Knockout Tag Team Championship is a perfect example of what a women's tag title would be in WWE right now. Hell, it might be even more useless.
I also see no need to bring back the Cruiserweight Championship. A title strictly for smaller guys comes right out and sends the message that little guys can't hang with big guys. It's something that just doesn't make sense to me in pro wrestling when you look at all of the various "little guys" who've been big stars & World Champions. Backlund, Savage, Hart, Flair, HBK, Jericho, Mysterio, Guerrero, Hardy, Punk, Bryan etc. have all been big stars who've been World Champions in major wrestling companies, who've beaten "big guys" with most of them being about the 230 pound mark or less.
The Hardcore Championship was a joke during the Attitude Era with the 24/7 rule. It's hard to take any title remotely serious when it changes hands more than 200 times in less than 3 years. Plus, hardcore wrestling isn't exactly in style these days when you look at all the wrestler deaths the past decade or so. With wrestlers not bleeding anymore, with shots to the head banned, it doesn't exactly come across as "hardcore." WWE can still put on great hardcore matches without blood, but part of what makes them that way is that they don't happen all the time. Otherwise, the novelty of hardcore matches without blood or insane spots would soon wear off.
IF WWE does go back to having one World Championship, then more emphasis could be placed on the IC title. Personally, I'd either unify it with the US title and retire said title, keep the US title but use it for mostly lower mid-card guys while keeping the IC title for upper mid-card wrestlers or retire the US title and create a new title for lower mid-card guys; like a television championship or something. That's generally how it was back in the day with Mid-Atlantic/WCW.
