I am having fun with the demo.
There are a few things that bother me:
1) Artillery is too powerful at long range
2) Good quality units leave the battlefield without taking any losses, and not being shot at.
3) I flanked the Austrians in Tutorial 2 - an infantry regiment advanced near an artillery company, on the flank. They routed without being shot at, ran in front of the cannons and lost 1000 men when the Austrians started firing. The Corps AI then sent a reserve regiment to take their place. They also routed, ran in front of the cannons, and lost about 1200 men. This happened again, for 3 regiments total, and about 3500 casualties. Those 3 regiments then marched off the field...
4) Infantry facing the wrong way when shooting
5) Infantry close in with the bayonet, but they can stop and not do anything as the enemy fires volley after volley. I think the Regiment AI is confused, and when the battalion in front loses many men, it halts them to bring up the reserve battalion....but they all end up shot to pieces and run away.
6) Units try to rally in range of enemy artillery when they have room to get out of range
