So Hulk Hogan and Bischoff should just leave in the middle of a storyline that they are involved in? Oh wait let me guess... when that happenes you'll start bitching about how TNA let go of 2 personalities who were involved in a major storyline.I don't think Eric Bischoff will stay through 2011. It's time to move on and the changes that he made haven't worked well for TNA, especially that some of them no longer remain.
Hulk Hogan needs to go too, especially on medical grounds. It's a reasonable solution and we do not need to see Hogan being plastered over everything again. It sucked hard and the Immortal storyline is just horrible. It's time to end it in a few months time, Hogan and Bischoff can then make their departure and TNA will have to fix the mess that they left.
Bischoff is not the head of creative, so I really don't see why people bring him up to blame TNA for not hitting 1.4 ratings on a more regular basis. You could probably blame Hogan more as he probably has a deal which gives him TV time, but Bischoff has improved TNA's game in terms of presentation, broadcasting, bringing back the 4 sided ring etc...
It's not Bischoff's fault that some of the TNA wrestlers like Jay Lethal, Doug Williams and Amazing Red simply don't cut it in the mainstream.
