Fact of the matter is that the amount of paint in the air during the NXL games in PA seemed to be less with the FA Set ups, than with the previous set-up everyone was using.
The FA thing takes a bit of the skill out of things, keying and running and shooting seem like they would be really easy with FA.
I see the differences between the leagues tech-wise as the differences in the major racing leagues with regards to the technology that is allowed. Nascar is much more limiting on technology than IRL or F1 is, it's all cool, just different.
