I might be delusional but I went through a couple quick battles (and i mean super quick) and the infantry appear to be behaving more rationally, not just that they keep their distance from each other. but they move abreast and contact with the enemy doesn't involve just one guy running into concentrated fire, with the rest of the team mile behind anymore. they seem to shoot on the move more, and are more liberal with those grenades. its kinda refreshing. so props to BF for making what i assumed
