I like the idea of "support tank" as an explanation of what SE might have been going for; however, the devs refuse to elaborate on their intentions, leaving us with "yea, we intend to adjust it".

The problem with "support tank" is exactly as Kaetara suggests, why even bother? With the exception of very few, party formations in most fights that benefit from a tank stack as much DD as possible. While I personally don't agree with doing this, I've seen its results and ya, they get the job done. So where exactly does a PLD play in to this? They become the weak link, they can't deal any significant damage, and most would just swap for an extra DD-type job.

SE's supposed original intent appeared to paint PLD as a tank, but WAR is obviously the real tank based on the current system. Jobs were supposed to clearly define the role of each job, so PLD and WAR can't both be tanks, just like WHM and BLM can't both be main healer or nuker.

Are Japanese players were supposedly upset by all this too, so in all likelihood, us non-Japanese players will just have to wait until their suggestions are heard and responded to before we get the shortened explanation from our community reps.
