Again I would add that my biggest complain now is defensive formation or better its efficiency and strength. I can see it almost in every played battle. Everything goes rather fine when two opponents attacks each other, but when one of them turns to defensive formation, in the same terrain with the same obstacles and objects it gains some kind of big statistical bonus and immediately causes huge losses to attacking enemy opponent. What is worse, even unit in square is able to destroy evolved opponent infantry unit almost without suffering losses for itself. So, when one army or part of it turns to defense, you can just end battle by yourself, I find it quite unplayable since then.
I noticed some strange manoeuvring by some units, too. It seems to me that some unit (cavalry/infantry/artillery) is so focused on selected opposition unit, that it just isn't able to see surrounding enemy units. So this unit just changes formation or even relaxing in the wrong place at the wrong time just in front of enemy, and of course this unit suffers great losses because of it.
