I'm not sure how you can play a fantasy game without Army Lists.
Very, very easily. They're a hold over from older games that were full of charts and percentage modifiers meant to replicate specific historical battles. To your point, playing a Fantasy game
with them makes no sense to me.
I make and decide on the troops I use. I do not want to pick and choose them from a list, limiting my choice, where someone
allows me to use my own figures. It doesn't matter how many choices I have (except I can't have more than 50% of those, or 11% of them, or 18% of left handed ones). A cage is a cage no matter how gilded.
They
aren't necessary. I do not like army lists.
But these rules use them, and
a lot of people really like them, so they will probably enjoy it. That's why there's more than one ruleset out there, because different people like different things.
The area movement I find interesting. I would like to see some AARs to see how it works out in practice. Also, I just like reading AARs.
