I like supply3 as u get the amo and health when allies capture cp
as thats a good thing to have there i feel.
on the server i admin in i just added xposed and it seems popular
some changed maps like super goldrush can be fun ,as well as still play out the obj.
Grave robbery is enother thats nice as well as frostbite ,v2base ect.
There are so many great custom maps out there and hopfully more to come,and everyone has there fav so its trial and error on ya server to what players would like to play .
Have Fun
cheers
