Before I voice my opinion, I'd just like I cam up with this thought after the 1st post, and I am not a sheep nor lamb...
TNA has no reason to get rid of the X-Division, nor the Title. The X-Division is the reason people started watching TNA. Imagine where TNA would be without guys like AJ Styles, Christopher Daniels, Low Ki/Senshi or Kaz? It would basically be WCW ripoff with a Six Sided Ring. Without the X-Division, TNA would've died before it could run a monthly PPV. The WWE would have signed most of the workers to contracts, and that would have been it. Now, onto the positive...
Without the X-Division, TNA will be able to have a PROPER Midcard title with creating backlash from anyone. Guys like Roode won't be stuck in dead end feuds, and guys like Storm won't have to always be in a feud. More potential
wrestlers from WWE might join in the hope of holding a Title, and helping to increase the popularity of TNA. While some of the wrestlers may not be suited for the TNA, and fired subsequently, more guys like Test may join and help to put other guys over...
But those these cases are unsure and unlikely. As odd as the X-Division scenario is unlikely, until TNA gets two hours, nothing will be certain...
