He should of just Bought WCW and kept it running seperate instead of Raw and SD.
THIS is what should have happened. There should have been no "invasion" or any similar bullshit. NWA/WCW had such an amazing history that it should have been allowed to continue.
There had to be some interaction, knowing both "Companies" were owned by Vince, the fans would have demanded certain "Dream Matches".
did any of us in 2001 actually want WCW to continue?
Then, no, I didn't much care. At the time I was kind of gutted that the roster I loved and enjoyed might get bloated and filled with guys I didn't know or like and not having much access to it at the time I didn't have any emotional attachment to the product or the wrestlers. Looking back now though with what I've seen I feel differently, I am attached to the product, although by the time I catch up to 2001 I might change my mind again 
Vince killed off WCW - in 2009 that was a mistake, but in 2001 it was probably the right thing to do - end the suffering, in the same way we'd all support ECW now being axed
Such is the nature of decisions - they can be right at that moment, but wrong years later...
