Other then Mijin , I agree with most that has been posted here, except for the WAR generates more hate faster. This is situational. against mobs that have high def, the better tank is most definatly PLD. I think people are trying to compair apples and oranges when it comes to hate controll between the two. Again, anytime damage delt flux's soo will WAR's hate controll, the less damage WAR deals the less hate it generates. Also, PLD is the only job that gets a TP boost for getting hit. wich makes it even more suitable for high def bosses. When war relies on tp moves like "steel cyclone" to generate hate. then damage delt > tp is vital to its hate generation. Soo obviously any time you gimp damage delt , again, you gimp WAR's DPS and overall hate gen. The biggest downfall to lossing TP gain per DPS for WAR is speed in wich it can pull off the TP moves, WAR will have to spend more time doing normal attacks and relying on buffs to generate tp and less time actually doing TP moves.
I said all that to say this, reguardless of lvl, def, hp, ect ect, of the boss/mob your fighting , PLD's hate generation is consistant across the board. when it comes to hate controll PLD is self reliant for the most part and dose not need outside influence , like increased dps to generate tp faster, to maintain its lvl of hate. I challange any level minded pair of tanks, 1 war, 1pld, to attempt to steal hate from eachother on a "mini boss" like Deepvoid Slave, Princess, or even coin counter. I think most will be suprised to see the results, I however wont be, because I have tested hate controll on both, and it was exactly as I suspected. LVL 60ish or less mobs, WAR had the advantage, but once you got into the "mini boss" range PLD held hate FAR more superiorly then WAR simply because, enless you gimp war's def to add to its DPS, it can not keep up with the dps to sustain the same amount of hate generated.
I have heard arguments that " well if you triple meld materia to armor you can sustain the stats needed to make war a viable endgame tank" to wich i answer "at what cost" not just in gil, but in stats you should be stacking to survive... at what point did we lose track of the true purpose of the tank? I agree this is partially SE's fault for giving incentives for "speed runs" but mainly the communities fault for being soo damn lazzy they went with what they saw as the obvious answer and have become soo blinded to the limits of the WAR tank. Soo much soo they are willing to sacrafice survivability to maintain DPS on a tank. This sacrafice is felt all around. Less REAL DPS to take the boss down faster, more healers simply to make it LOOK easy. And for what? other then ego I can not understand why people are soo head strong on WAR tank for content it realy is not designed for.
Soo yeah, make fun of my spelling, IDC, try to counter with " nuh uhh, your a doo doo head" IDC, come at me with real solid numbers of damage taken and prove that you can keep WAR's dps up to par as well, and I will acknowledge your claim till then, its all bs. Dont make somthing outa nothing. and if it aint broke dont fix it.
