I disagree. I don't care how much I pay, I'm not beating GMAC. Unless I pay him directly to abstain from the competition
I think you're right in that if you want to compete for the top 5 - you need to be willing to invest in Ironite. But to actually WIN Eternal? Or even jockey for which top 5 spot you get? That takes skill. And speed is a part of that.
Maybe it's just my bias, but I don't think you can take any Level 100 or above player - hand them some Ironite - and say beat GMAC, Caliza, Black Steel, Kamuz, Carlos, etc. They're not going to be able to do it. And ultimately it's not about who had the highest win percentage - it's who accumulated the highest number of points. And while you have to pay to enter the competition - buying a stock load of Ironite and then not being able to keep up is a real possibility if you're not used to the Saturday race.
