I liked it.
I'll admit it, I care about my score. I try not to, but I do.
Before I was reluctant to head into the MW arena because I didn't want to kill my score by messing around in MW planes. But, this tour I spent quite a bit of time in there since my MW score didn't impact my LW score.
I actually did better in MW than I would have thought. I liked having the scores split because I could go into MW and 'goof around' with planes that I routinely get killed in in LW, and I could isolate those kills from my LW score where I'm all business.
I know this is utterly ridiculous, but I might as well be honest.
I actually found MW to be a very fun arena. Smaller numbers meant that you could have a good 1v1 fight, kinda like a MA AvA environment. And, there's some really good players in there, moreso than the LW MA it seemed like.
So, there ya go, my $.02.
