The REAL real problem with PLD is not gear, we get some pretty great gear, it's not DD capability even, Chant do Cygne, if you bother to get it, is an extremely good WS an can really dish out some good numbers both inside and outside of Abyssea. We don't need gear with more enmity on it, we've got more than enough. We don't really need much in the way of damage mitigation either, we've got that aplenty. We don't even need job abilities that generate more enmity or keep it from decaying as fast as SE seems to think we do.
the REAL problem with PLD and i hope SE is listening to this, it would make a first, is the enmity cap. Every job in the game caps enmity at the same amount. And lets face it, even the most pimped out PLD is probably not going to reach that cap faster than a badass DD laying the hurt on. When everyone caps enmity at the same amount the mob just bounces around between whoever happens to hit it next. THAT is the problem with PLD, and until something is done about the enmity cap and how enmity is calculated PLD is not going to be doing much real tanking.
What PLD REALLY needs is either a.) an ability that can regularly (every 15-30 seconds or so) lower the enmity of ALL other party/alliance members, or b.) a higher enmity cap than the rest of the jobs, either through job abilities, or traits, or whatever. Until that happens, there is nothing AT ALL that can "fix" PLD as a tanking job. No gear, no job abilities, no DD capabilities, no spells, no damage mitigation, no anything else will make PLD the top dog as a tank until the issue of the emnity cap is addressed.
That is the REAL real problem with PLD.
If you're listening SE, THIS is what PLD needs, not some job abilities that keep other party members from getting hit, not some ability that keeps enmity from decaying as fast, not some mediocre changes to an ability that was never practical to use, even in the old days (cover), or anything else. You need to change the fundamental way that enmity is calculated. THAT is the problem here.
