I hope not. More belts make belts less prestigious.
How is having tag team belts for the women making the other belts mean less? There is only 1 belt on each roster! It doesn't affect the other belts at all, those are the men's titles... I also thought that the brand extension was a bad idea at first, but honestly it's not doing so bad right now IMO. And while were fully in it, why not go all the way and try some new stuff? Add women tag team titles, I don't see anything wrong with that. People always complain how the women can't get over, now there's a rumor of adding tag team titles for them and people already complain...
WWE doing it as they are is a bad idea, I am not saying never have them - Just now right now. They have to fix all their other crap before they attempt anything new like this that will be long term. Testing matches at PPV's like a women's RR, that is fine. Nothing is set in stone. They introduce new tag belts and muck it up, they can't exactly just make them disappear.
Get rid of the brand split first, then you have more women going for just 2 titles. SmackDown has 11 women right now, just 3 tag teams is 6 women leaving 5 for the other title and other roles. Not enough.
