Im more interested why it became more difficult in 08 and 12. Because these are the specific years handicaps were being applied, not by Ducati or Honda, by Ezzy, to aid Rossi. Thus the relevance to the thread title, negative repercussions for GP, specifically by the Rossi fan base. Changing rules are bad for the sport in the long term.
It's nothing to celebrate to me that a rider was able to remain competitive while the odds were being stacked against them. It had greater negative repercussions than those to Ducati, for instance Kawasaki immediately left the sport.
Krops wrote a great piece on it. Negative repercussions. Again, we see PI should be one of the all time great races, a true classic. How the hell did we get from that race, one to celebrate for the ages, to the present, calling for a riders head? Because to many one rider is more important than the sport itself?
