While you are correct, it is hard to advance and enjoy the game thouroughly without cooperating and interacting with other players. If your setup is undesireable to them, then there is no reason for them to play with you, and therefore your own enjoyment of the game will suffer.
It kind of sucks that some of the advance jobs don't make good subs. It would have been a lot cooler if there were more efficient combinations out there. I'm a pld and I get annoyed that /war is the only sub that can be used.
