I haven't played the west side yet but i have played the city so i'll give my thoughts on that, i think they changed it too much, the buildings are way too spaced out now, and the part that was previously a full circle is only a quarter now, i'm not asking for old Kharkov back, just that they push the buildings closer together and fill in the outer gaps so you don't have to worry about being shot by somebody you're not fighting.
