I think the bugs of the game kinda let people down. One of the things that made RTW so revoultionary was the AI, when M2TW came out I think everyone expected the AI to be just as revolutionary.

The problem is that there are a couple of bugs with the AI that didn't happen in RTW. Infantry Spacing, Passive AI, etc. I was slightly disapointed by these things.

Also, I think CA could have benifited from explaining the changes to the game to the RTW crowd a little better. There are a lot of little details that have changed from RTW, and I think everyone is going in thinking this is going to behave just like RTW. I still don't understand how the whole walls/towers thing works compared to RTW.

All this being said, I still think M2TW is awesome. These are just minor flaws on an very sweet game. It sounds like CA is trying to address the problem and that means something. I just think once they patch the bugs this game will be even more awesome.
