I really want to test this out, and tt shouldn't actually be all that hard either, given a decent parsing tool. All it requires is finding out whether there is a straight up cap to parry chance (easily done by just getting attacked by a low level enemy) and then testing out whether that cap is present when fighting enemies that are "harder" (e.g. the same level as you). You could test it further by slowly reducing your parry rating and seeing if parry chance goes down immediately or whether it remains the same until you go under a certain number.
That seems really low to me, even for a PLD. In tank stance and using i90 pure tank gear, I regularly manage 150 DPS as a WAR; my PLD friends manage ~120 in similar circumstances. The only time they don't get those numbers is during AoE scenarios or those with extended downtimes.Typically I achieve 85 DPS with Paladin, if I can up that to 120, I would say that's not just acceptable, but preferred if it only means dropping off the chance to parry a negligible amount.
It should be kept in mind that most of the slots in the two i90 sets both have parry rating on them whereas there is only a single slot in the 110 sets that has parry on both sets (Body); for every other slot (not counting Ring, since you wear both of them), either Noct or High Allagan is lacking parry rating. As such, just listing total parry per set isn't providing an accurate measure of what the devs are "providing" for the given tier.Those numbers should be indicative of something a miss here, they wouldn't just up ilvl while down grading our mitigation would they?
There are only 2 reasons I can imagine for the devs to deviate so far from what most would consider to be the "proper" way to itemize tank gear (e.g. lots of parry and acc; very little det, crit, or speed). Either the devs want to force players to both spend soldiery tomes and run content to get functional tank gear (either of the i90 sets works out quite well; going either full Noct or full High Allagan is a bad idea) or they are trying to send a message that stacking as much parry as we have been is basically wasted and are designing said sets to "encourage" players to stop doing so.
