Let's debunk a myth here. TNA Women are NOT better wrestlers than WWE women. In fact, a good percentage of them were and are WWE castoffs (ones that were in development but couldn't cut the mustard). I also find it amusing that there's a love affair for the wrestling of Awesome Kong. If she was a male (which she actually might be), she would be the exact type like Big Show, Khali, Kane, that everyone seems to be bored by. However, since she's a woman, we are in awe that they let one that looks like that wrestle. Quite honestly she's limited in what she does and puts on just as entertaining a match and you might see from Beth Phoenix.
The one thing TNA does do is give their Knockouts mic time to develop feuds and stables of women. It shows more focus on the division and even if you are someone like Madison Rayne who wouldn't be in the title hunt, you are part of a stable and thus can have stories based on that. Think about this, Mideon was useless in the WWE for the most part, but he was on TV every week with the Ministry. Being in stables helps people get over. Right now, the ever improving Eve fighting Natalya is great because their respective teams are feuding and thus, them fighting makes sense. No titles, just bragging rights for the team. That's a FEUD! Sometimes feuds involve a title, but not always. If there becomes more of that, I think you'll see that the WWE Divas and TNA Knockouts are about even talentwise. Some great, others not so much.
As for whether we are "lowering our standards"-NO. I think the top divas today like Mickie, Beth, Melina, etc. could match up with the top divas of any era. In my life I've seen Alundra Blaze who was awesome, then Sable and Jaqueline brought back the women's title and Sable was probably the best diva i've seen and not just because of them implants. She wrestled quite well and without her, you have no Victoria, Trish, and Lita. Maybe Lita because she wrestled independents and is the female Jeff Hardy. However, for modern divas, there are a few that take us based on their looks and ability, but comparing them is like comparing Hogan, Austin, The Rock, and John Cena. For their own times, their respective styles worked and they became the best. We can always argue who the best was and is and everyone will have a different opinion, but I don't think it's a dead given taht today's women are somehow the worst ever. In fact, I think there's more GOOD women wreslters today than ever before but because of that, writers struggle to find stories for them all so we just see a title feud and not much else. Perhaps that will change and that's the one thing WWE should look at TNA for: utilization. But I would NEVER say the talent pool is that uneven.
