Yes it was using your new battle stats. I don't know the exact time, but defiantly no more then maybe 25-30 minutes tops, as soon as i started to flank the army, they routed very fast. Whatever the case, the battle did not drag, like it can for siege battles. However, I still haven't tested your new stats in a actual assault/siege battle (As I'm usually waiting for them to come out towards me, as it's far easier to kill em like that) yet, so I will see how that is.
Ironically, I ended up having to play the first battle Twice , as the first time I won, I got a CTD after the battle, not sure if it was because I took way to many screenshots (That were useless in the end, as they all ended up Black screen ones), that in turn it screwed something up, or was it something else entirely. (I doubt your new EDU would have caused that), when I replayed the battle, and then the 2nd battle after, it was smooth sailing then, but I also limited my screenshots on purpose.
