Most people are taking issue with the fact that, in the course of six months, Nikko went from being a free thinking, mad genius, to a complete idiot in the eyes of the gyromaniacs. He is no different today than he was six months ago, or six years ago. The very same person with the very same assets and the very same flaws.
And since you brought it up, he has been using discs from non-sponsors where MVP had comparable molds available. For example, he could have mixed an Axis into his bag, but he chose to go with a Claymore instead. One can understand him throwing Innova because he used many of their molds for years, but why in the world would he be using a Claymore over an Axis?
For the rational, the answer to that question is painfully obvious.
