This can be seen in two differant lights by two differant kinds of fans. Let's compare them. We will call our first group of fans Fan A and our second group of fans Fan B.
Fan A sees this a major way to undermine the X-Division. Their views are to get rid of the X-Division title. Better yet, why don't they get rid of The KO Tag Titles as well? Also, get rid of the Legends/Globa/Television Title. It's obvious that no matter how much TNA says the X-Division matters, it doesn't. The X-Division does not matter in TNA! At this point in time, the X-Division is nothing more than a mid card title that keeps mid carders semi busy. Hell, the X-Division is no where near the size that it used to be. On it's own, the title made sense early on in TNA's history, as the indy guys they brought in helped distinguish them from WWE, but now it shoehorns people into a certain style, and it's time has passed. Fan A doesn't like Abyss, Fan A likes cool spots and Fan A is very unhappy.
Fan B sees this as a good idea by TNA. Fan B isn't taking the pessimistic view and sees that Abyss will add some much needed attention to the X-Division with his mass domination and people will want to see the small puny X-Division stars eventualy take him down like how they took down Team 3D all those years ago. This X-Division thing has really shown talent in some stars we never really saw e.g Brian Kendricks excellent promo skills.
I'm more Fan B.
