It's definitely a come back from bf4, we don't talk about hardline...
it's a little bit.. laney, but it's forgivable because the maps work like they used to in bf2 for the most part, i.e. combat areas are more isolated from each other by terrain/fog. Where as bf3/4 it was all about you can see almost everywhere on a map at any time.
There are of course exceptions to that rule, but for the most part the fights are fairly isolated.
64 player servers are still complete chaos and have far too many/frequent vehicles.
40 player seems to be the sweet spot for the map sizes.
Just get the base game for now, no need to purchase the all-in 100 quid edition yet.
