I know I'm in the minority, but I much prefer a season with two to four riders going toe-to-toe vs a season with almost random results. If it's a tight battle with a few top teams, there's no doubt you're watching the best duke it out. When it's any one of seven, with riders bouncing between podiums and out of the top 10 round-to-round, then it's a lot about luck and hitting a setup with a bike that works with the tires for that track on that weekend. For that, you might as well watch NASCAR.
The legendary seasons are usually about two or three teams fighting tooth and nail. Roberts vs Sheene, Spencer vs Lawson, Rainey vs Doohan/Schwantz, Edwards vs Haga/Corser, Rossi v Biaggi/Gibernau/Hayden/Lorenzo. For the parity seasons, it's usually the steady guy that wins (Roberts Jr., Mir), which is a lot less fun than the crazy guy who wins or crashes.
Don't get me wrong, parity is more fun than one guy crushing everyone else. But I like the heavyweight fights between teams with different strengths and rider styles. If someone were to step up and take it to a slightly weakened Marquez, with a solid package, that would be my ideal. My worry is that the tires and cost-cutting will result in another free-for-all where the guy who finishes 6th to 3rd every week wins the title. I want to see guys riding the wheels off the bikes, not playing tortoise to the hares...
