Simple stuff like not being able to flank unless you have a giant free area, veteran units still getting wiped by non vet units, basic stuff that you should be able to use to win fights is poorly or not implemented.
Especially the flanking is horrible. The whole concept of the Roman cohort was to allow units to be flexible and take advantage of opportunity but in this game you need a square mile of empty space to maneuver.
Musket smoke got it right this game is just frustrating.
