The only value of PLD in the current game (which is about to change in three days) is to charge your Limit Break gauge faster.

When you see claims that WAR can tank everything wearing full STR accessories and in their DPS stance and healers supporting that, you know that the PLD is broken when the producer of the game frankly tells you that low PLD dps is the job's identity.

Make no mistake, the full VIT PLD is very valuable in the DF when you don't know what the healers and DPS are going to do. But in a static, it seems to be the consensus that you're just better off with a WAR. Anyone who talks about how important tank dps is and how healers have no trouble healing any tank in dps stance the full time, is necessarily saying that PLD as a job is completely unneeded and a hindrance to the raid.

If you say tank dps is important yet play a PLD, you're wilfully gimping your raid dps.
