I think the really problem with pld is the lack of damage. War do more damage but take more than PLD, PLD can keep alive itself for a bit more healing and helping to heal other melee jobs with his ability but a lot of events consist on try to deal a lot of dmg fast or you're dead.
On moogle you need to kill those faster as you can before 2h or you're dead, ok, BLM do a lot of more dmg than war but a bit of more damage helps.
Garuda, need to take it down to 50%-60% so she can do her 2h, also steel cyclone helps to kill plumes and garuda clone.
Then, speed runs, war can do more a lot of more damage so people will want it to clear AV and CC faster for speed run.

It seems that on the game to do it better you need to kill it faster and this is the problem now, pld lacks on damage, but isn't his problem, paladin should be a wall and with this a lack of attack power. Speed run and doing more damage so you can win pretty much obligatory should be removed for a more strategy and peaceful oriented game.
