I think it is good that TNA is going to invest some new titles for their female division, which tells me that TNA values it's female wrestlers skills more than their looks.
Secondly I don't think TNA has 7 titles I don't count the IwGP Tag Team titles as TNA titles because pretty soon they will be back in Japan where they belong second. I think TNA needs to add an X-Division tag team titles and everything will be set.
As far as them having all these titles, there is nothing wrong with it because you those titles as stepping stones for the bigger title. Oh yeah WCW only had 6 titles
World
US Heavyweight
Cruiserweight
Cruiserweight Tag Team
World Tag Team
World Tv title
And no TNA is not like WCW 2000 they are ten times better and they are getting better and better with each show!
