I voted 8, may be I should have been more generous.

It has gone further than I hoped in improving the battles - the balance between cavalry, missiles and infantry is nice now; apparently phalanx AI is better too. Unlike Duke Johh, I include this with my rating of the expansion as in the past, expansions have been valuable mainly as patches (the fact that 1.3 will be available separately is another plus in my view).

As for the actual expansion campaign, I think it is meatier and more interesting than either MI or BI. Hordes are innovative and challenging. Great stuff!
