Play what you want to play. I have both PLD and WAR at 50, but I still play WAR. I *know* that WAR brings nothing useful to the table that PLD doesn't bring (or bring more of), but I don't enjoy PLD; I enjoy WAR and, because I play games like this to *enjoy* them, I play my WAR. I would enjoy my WAR *moreso* if I didn't feel like I was bringing the effectiveness of groups I join down, but that's not enough to make me swap to a sword.
