You are only demanding homogenization.
This post might seem angry, but I'm more just weary. I have seen this exact same situation play out before. Rewind to 2008, World of Warcraft - the closing months of the Burning Crusade. Three different tanks that played three different ways, which meant DIVERSITY and variety. But you can't have variety without imbalance.
Some people...the imbalance is all that they see. It's a form of activism, an injustice to be fought - they take to the forums to post petitions and champion their cause: "That tank can do a thing my tank can't do! UNACCEPTABLE! FIX IT!!". Even if well-meaning, the suggestions they make are short-sighted, focused only on the other tank's toys.
Anyway, Wrath of the Lich King rolled around, and and suddenly, all the tanks were exactly the same. Same mechanics, same "oh-shi" buttons, same same same. My Paladin could do everything my friend's Warrior could do and vice versa. All that was left was different animations for the same mechanics.
Any of this sounding familiar? "PLD needs DPS like WAR, PLD needs the same debuffs WAR/DRK has, PLD needs <existing advantage other job has>". It's like looking back in time. "Paladin needs Shield Wall, Paladin needs Last Stand, Paladin needs Spell Reflect". We know exactly how that dance plays out, yet here we are with people loudly demanding to do it all over again.
Are things balanced at present? No, of course not. But our response to that should be constructive, creative suggestions that try to push the tanks FURTHER APART, not closer together. Do you want your PLD to be a WAR in shiny armour? To be exactly the same? I don't think most of you do, I think you want your PLD to be a PLD and be competitive in itself. So why all the "give us more DPS" posts? This is the simplest solution, but also the laziest. The thing you're asking for will eventually destroy the uniqueness of the job you claim to love so much. If SE listen to you, as they've said they do, then you are advocating to make the game more boring.
The people who post solid suggestions that increase PLD's raid effectiveness while retaining its defensive heart are a vast minority, from what I've seen while lurking here. But they are the ones who really need to be signal boosted. Not the people asking for bigger numbers.
You guys might think that you have played a lot of games and you therefore know how to design games. YOU DO NOT. Those are two different things. If you don't believe me, try making some games. It's really, really hard. This will probably ruffle some feathers because people generally don't like being told they aren't special. The truth hurts. This game is exceptional, and I mean that both descriptively and statistically. 95% of us could not build what the SE devs have built here so far, let alone do better. If it were that easy, there would be many MMOs better than FFXIV available, and we wouldn't be here arguing about this stuff in the first place.
FFXIV devs, if you see this: please never make the mistakes that were made with WoW. I dearly loved that game at one point, but once the players broke its back, it was an endless cycle of tiny "conveniences" based on forum bandwagon complaining that ended up making the entire experience trivial and meaningless. Death by 1000 cuts. Eventually all classes have a stun, a snare, a self-heal. Everyone gets an Ashbringer. All exactly the same except for the animations: shallow, homogenised, and above all, dull.
Is that what you all want for Eorzea? Think about it, please, next time you make a "moar DPS for PLD" thread.
