So you're saying TNA should downplay the importance of a storyline that involves the ownership of the ENTIRE company? My lord, you are a genius, aren't you?
What did they get from it? Well let's think kayfabe, not smarky smark. Hogan and Bischoff are egomaniacs, they want power and money, like they did in WCW when they were heels. They used Dixie Carter in order to gain control of her company, therefore get power AND money which she will provide, that's her job. That's what they got from it.
The actual pay-off will be the rub the faces (most likely Fourtune) will get when they take down Immortal and give Dixie her company back. The evil villains that came to take over Wonderland are going to be driven off by the mighty heroes who made it what it is.
Why do people even THINK about shit like that?
