Battle of Rossbach - new Historical Battle for Empire Total War

I played this new battle that comes with the 1.4 patch at the weekend. Much like Fontenoy it seems too easy. I think this is because the quality of the Prussian troops has been put too high. You don't really have to be too clever to win it.

The set-up for the battle is also a bit bizarre - with quite a few large mountains really defining the battlefield, and I am guessing, forcing the enemy AI to act in a certain way. This works as the cavalry try a flanking manoeuvre, which fails, and then the infantry deploy badly in a sort of shaky column, which is quite easy to defeat.
