 It can be useful when you have applications that don't know how to talk
to different members in a load balanced service. Imagine how simple load
balancing would be, if you had ten webservers in a load balanced set, each
with a unique ip, all round robin DNS'd to the same hostname. 

 If programmers would just get a list of all IPs associated with a
hostname, try the first, attempt to connect, and if that failed inside of
a second or three, try the second etc. - everything would be rosy. But no.
People are lazy. So, you have to do NAT etc. to get around it. It's a
crazy world.
