the BAI is good, still not human-like but good enough to make me lose a few battles even when i had the advantage.
once, as France, GB routed my entire left flank with MILITIA, after they pinned my right and center with line infantry and applied 8 units of militia to my 3 line infantry holding my left flank.
yea, i couldnt believe it either.
but all i had to do was wheel my right flank around a crush them.

but there is a problem with the "no forts" mode where the enemy will just hang back no matter if you are bombaring them to death for an hour.
