Was there a point to your invective? Because if so, I don't see it. Invective like this is just rude and contributes nothing to the conversation (which is why it's generally frowned upon in formal debate settings and in general polite discussion).
And that's well and good, but that doesn't change the fact that having an identity as "the defensive defender" is shallow, redundant, and pointless (WAR is "The damaging defender" and DRK is "The magic defender", if I had to use *gasp* another analogy). Passively taking less damage is well and good, but would more interesting gameplay be a bad thing? We can passively mitigate more damage than the rest, but the job itself is otherwise flavorless. There is absolutely nothing unique about PLD right now outside of their external healing ability (which is clumsy and easily interrupted), and their slightly enhanced physical mitigation (thank you shields). And I think that's why a lot of people, myself included, wish that they'd do something to change it.
