urban combat maps

hello, before i start i might be asking way to much here no experience in any of this just throwing out suggestions. 

what if  the bf2 map karkand gets redesigned opening every building there is or just a new map building 5 stories high with full acces. or the kairo map opening/rooftop acces on the buildings.  i personally would enjoy it alot. might get a little paranoid having to look into every window there is but for groups it would set up opportunity's to create ambushes. for us ''solo'' players it would get harder but i think it can be really fun. i do enjoy these big open maps but kinda missing something like floodzone from bf4
