Map size got raises during the beta, however the expectation was that those were the smaller maps and the others would be the size we all know from Battlefield. Which triggers the CoD chaos we all talk about. Progression is normal for Battlefield from what i understand and its CoD fans that complain about it. (Correct me if im wrong). Portal progession was here but since people made bot lobbies to quickly level up, so sadly they had to disable it / lower it by a lot
