Depends on many things as already stated... whether or not you can lane people out off break, does the field allow moves or does it force stand-offs, how aggressive is your team and what is the level of competition.
If you have some decent forwards and play you should be able to get by with 3 pods on your forwards and 4 pods on your back players but don't let folks carry less than that.
If your team is kinda slow you will want to carry more paint because you will need to gun battle people out before you make moves.
Im an amatuer but I am curious, generally better players like d2 and up shoot more or less?
Way more... they roll their guns a lot more and the players are all smarter and tighter (harder to shoot).
