Not going to change unless they focus more on PLD, since the other problem is it has lower base HP than WAR does which gives it a slightly better survivability rate by default, but a good PLD is still a valuable asset to have. The main thing regarding WAR is it's also a DD which based on how enmity works in this game (as well as XI) damage is more constant generation in the long run which is what put WAR ahead, but PLD can work better for single target mobs if the PLD itself is well geared and prepared.
