Okay I edited my earlier post with correct figures, I did fat finger a 5 instead of 8 on the Number pad, I just don't know how that carried over to the rest of the calculations. lol
Even though I was trying to reassure the OP that enmity "is not an issue", I did, by no means at all, not mean to say PLD is "perfectly fine" as it is. Its enmity "non-issues" against DPS in tank stance still does not solve its enmity issues if the PLD dares try to DPS without a Ninja feeding it enmity every 3 minutes.
That said, for all intents and purposes, PLD's enmity is fine if its objective is to hold aggro for a party in 4-mans for example. But if the PLD tries to push DPS against competent players (DPS and off-tanks), PLD WILL have issues because of PLD's inherently low enmity causing it to more time on enmity generation by resorting to lower DPS/potency Halone combos in ShO. I would definitely love to see PLD's enmity pushed up to be in line with the other tanks. If buffing Halone causes a problem in 50 and under sync'd content, then give the PLD something to make up for it above 60. I'd suggest small multipliers on Goring or RA. A double multiplier would be just enough to hold hate when coupled with other enmity generators but not enough to cause a problem when in Sword Oath.
I also mentioned in my earlier post that PLD's mitigation is not (far) ahead of the other tanks, if at all. Yes, WAR can burst mitigate "better" than PLD in some situations (specially against magical damage), however, PLD is far more reliable than WAR due to more lax timing and stronger effects. PLD is as reliable as it gets when it comes to mitigation. The PLD can do everything a tank needs to do, for the most part.
I don't think I have much to add to my earlier post, since I said play the class you enjoy the most in there. And that a class you're passionate about will probably push you to get creative with and push its limits over a class you do not like where you would end up spending the least effort as long as it gets the minimum desired result.
