@Naoki Yoshida-> Make Samurai a DPS class!!!

But if the reason for adding fending armor to SAM is that current tanks get even more perks, then we wont gain new tanks.Surely you must have realised by now that perhaps what we really need is a shakeup in the basic formula if we want more tanks. If dps jobs gets more responsability, the one thing that currently in my experience, then more tanks might get te see the light.

Because retaining your existing tanks is just as important as trying to get new ones. They aren't mutually exclusive, just because a system has a perk for current tanks doesn't mean that deters people from taking up tanking. Suddenly tanks go from a 3 for 1 gearing perk to a 4 for 1, which is great for current tanks, but also appealing to new tanks just as much, because they too can gear 4 tanks for the price of 1.

Dark Knight shows evidence that tanking numbers have gone up (as opposed to their downward trend from 2014 to 2015. DRK is also the most played tank, meaning it was absolutely a success. "Shaking up" the basic formula isn't guaranteed results, it's a gamble, and one people have been saying for FFXIV to do for all manner of things in it's game, from endgame, to dungeons, to other content, and time and time again SE has shown they are determined to take things a safer route. For them, it's better to stay the steady course and slowly sink, than try something wild and crazy to "shake things up" and inadvertently sink themselves faster.

SE has shown they aren't willing to hoist responsibility on DPS players in that they still refuse to add an in-game parser, which would put their effort on display for everyone to see if they're pulling their weight or not. Tanks and healers, their mistakes and flubs are all visible to everyone, and that's part of the reason people avoid the roles because of that additional pressure.

But until that day we cant just keep adding perks on perks, baiting people into tanking. Tricking them with goodies into doing the bad thing is bad! Its a game, its supposed to be fun to play. If people arent naturally playing then it must be the games fault at making them consider tanking.

If you can't have fun because someone else gets more/better stuff than you because they're taking up a role that you are choosing not to play, that's not their fault and it isn't SE's fault, that's your fault. It isn't tricking people into it, it's incentivizing them to step out of their comfort zone and to try something they might otherwise not.

And if the amount of tanks truely will "plummet" as you say, what hinders the dev team from adding a third dps partymember in dungeons? this will make the queues for dps 33% faster. Why continue with the same old boring ideas when you could have fresh ones?

I don't know, what stops them from just removing tanks from the game period then? The amount of work you're suggesting is staggering, so naturally they want to avoid that if they can. It might be inevitable in the long run but it's definitely something they want to postpone. Not only does that require retooling the entire matchmaking system and the party system, it would then require rebalancing every single piece of content because now you've got a whole big chunk of more damage. It's not a simple as just saying "More dps in the party!"

I'd like to see the list, as i am unable to visualize what huge benefits it will have, aside from the aforementioned ease of gearing.

I never said huge benefits, just numerous.
Keeps roles and their stats homogenous, this drastically eases balancing especially within the same role. This saves time in terms of itemization as well. It's easier to tweak and balance tanking jobs if they all share the same gear. Once tanks start using different classes of armor it becomes that much harder to balance them. Look at WoW's tanks for example, a troubled history of sweeping buffs and nerfs and a constant struggle as to which classes are the best and the worst. SE has shown time and time again they really want the game's jobs to be balanced even if it means they are less unique from each other. We still see people considering which tanks are best/worst in this game despite the 3 tanks being incredibly well balanced. This further extends then to fight/content design. If you have 4 tanks, yet one of them has overall lower defense because they now wear different armor, a fight that was designed with the first 3 tanks in mind, may now completely destroy the 4th, once again leading to a problem of balance which will then result in 1 or multiple tanks becoming completely unviable and a further stigma attached to tanking. So it causes a pretty big ripple, and it's easy for you to cut down the list by wrapping numerous benefits under the blanket term of "ease of gearing" as there's multiple facets to that.

tldr to all my points:
I want change and new reasons for newcomers to tank, as opposed to giving the existing tanking community even more perks.

Then perhaps FFXIV isn't the game for you, perhaps WoW would be a better fit. I for one do not enjoy working hard and spending tons of time in a game for then everything to flip on it's head into things I don't enjoy.
