You provided the answer by yourself..... when most of the clients are behind NAT then you definately MUST count with rtp/media proxy in your setup, because you are not able (neither willing :-) to control the NATs.
Depends havily on the client if you have to use it when: a) both clients are behind NAT b) any of the clients is behind NAT OK, let's say 90% users behind NAT... a) is then in 81% of calls, b) 99% of calls. Just an example. To prevent rising subsequent questions - check active/passive direction attribute in the SDP body.
