Man this is some deja vu...
Parry is a crappy stat as much as every other secondary stat is a crappy stat. Generally speaking the only time this isn't the case is when mechanics are directly tied into the stat - such as crit for brds/sch- and even then the difference isn't gigantic. The big thing here is that parry is the only available stat to increase your survivability as a tank. The fact that it is a small increase is not an issue, as the difference in dps from going for dps stats instead is also small outside of melded gear(which I will get to in a moment.) It's already small for actual dps classes, and it gets even smaller when you consider that you got a 20-25% damage reduction on you when tanking.
The next problem with this whole argument is that you rarely have a lot of choice when it comes to itemization. You tend to have a ton of stats that aren't "optimal" simply because the game pairs stats together in random ways. Actually trying to forgo parrry entirely for det/ss/crit only is a lot easier said than done unless you want to waste a lot of stat points on accuracy, so the actual difference you get from trying to optimize only shrinks further. The lone exception to this, and the only time I see a parry vs. dps stats being an argument worth having, is for pentamelded gear. As you can put a boatload of dps stats on that stuff that you can't normally get. But most people aren't talking about that, they are arguing over the small stat gains of two equal ilevel items.
Personally I'll always take the extra survivability on content that is remotely challenging, because shaving off 5-10 seconds(maybe) of an encounter thanks to my slightly better dps doesn't match the potential for saving a run completely thanks to surviving a hit in a clutch moment. It doesn't happen every fight, but I've seen it enough times now that it's something I like to have. But it's not a big deal either, unless you are absolutely min/maxing and wearing full pentamelded accessories/full 30STR, the difference either way is going to be small. So I'm not really arguing for or against parry here, it's a crapshoot either way. Better off just wearing whatever of equal ilevel you can get easiest, and not worrying too much about it.
I gotta comment on this though, another deja vu moment, except it was Wolven who claimed this last time I think.
I would argue Parry is not that important of a stat for Warriors. Warriors have a decent bit of mitigation with Inner Beast and the rest of their cds, especially the omnipresent Vengeance.
Stacking Parry when you could be stacking Strength, Crit, Determination, or even some Skill Speed seems like such a waste of time considering their HP pool and defensive abilities are more than good enough to shrug off everything the game has to offer at the moment.
With WAR it's all about that self heal game to keep you on your feet. It's a million times more reliable than Parry.
Noooo. PLD have way better cooldowns than WAR, and we actually get less value out of parry due to block rolls coming first. If anything WAR get more mitigation from it. Parry vs STR is never an argument unless you are talking about wearing dps accessories, and at that point you clearly got the content on farm/possibly out gear it. This is the same thing as the VIT/STR choice. If you got content on farm though it rarely matters what you are doing.
And for your final statement, no, this isn't 2.0. WAR self healing is not that great. If you are using IB correctly there is a chance some of that heal will be overheal to begin with, and even if it's not the amount is very small compared to incoming damage. WAR is definitely not about a self heal game. It's about predicting attacks and using cooldowns before they come. Our WAR gears for DPS but still parried more damage over the course of our last T8 kill than he healed from IB.
I like how most of GAF's houses so far are in Ul'dah.
All the good Limsa ones were bought super fast.
Bright side is now I can get Kawa or someone to water my plants.
