Itís pretty well documented that Vince doesnít like them, thatís why they donít have on the MR any longer. The ďKingĒ gimmick that was forced on nearly every winner of the KOTR was so, so bad, and would probably be done again.
If they can keep Vince away from that 1980ís gimmick desire, a KOTR style tournament is great for multiple reasons. You can help build stars, by having them beat multiple guys in a night and having strong matches. It allows you to do matches that you usually canít I.e face vs. face. And it gives more significance to a ppv and makes earning a title shot feel more important.
It honestly doesnít make sense for them to not do it. But... we all the know the moron that runs things.
