1. This is strictly about endgame.
2. This is not a rant about bleed on tank busters
3. This is not about the fights as a whole, but the off tank role on it.

On my time playing FFXIV endgame (Savages and Ultimates) I have come to really hate the Warrior job, and I know people will hate on me because they love the class, many times you'll hear that it is the best tank in the game, or the so famous "Warrior is F' good" but I really disagree with this, this job is in almost every static, in almost every party finder, almost every composition out there has a Warrior on it, and the main reason is because of how easy it is to play and how frequent it can cheese fights. I could go hours upon this idea, but to give one of many examples, last tier's 4th fight against Hesperos is a prime example, a fight in which Warrior could simply invul 4 of the 5 tank busters on the fight, having only to swap on phase 1, making the off tank be the so called "Blue DPS"

Here's where I really love Abyssos, despite how we can all feel that only 2 fights this tier are fun, one thing I can say about all of them is that the off tank got to be involved on the tank role! that's right, WE GOT TO PLAY THE GAME! and this is by the design of how the tank busters work, no tank can invul it and keep on tanking, a swap is a must on almost every fight, the one exception being 7 where both tanks are always on top of enmity, but what this means is Warriors can't cheese it, and therefore the off tank is not just a blue DPS, is an actual tank on the fight.

The sad part about all this, is that either SE would have to make this a design choice going forward of making tank busters a must swap thing (which I know is not unique to Abyssos mind you) or somehow nerf Warrior's sustain, which I don't see happening anytime soon, it is just so sad that one tank gets to have most of the fun all the time, and that tank happens to be the most boring and easy to play, where Paladins and Gunbreakers are heavily punished upon messing their rotations, Warriors are near impossible to mess up, and even if you do, it really doesn't matter, you can recover almost instantly or with near inconsequential repercussions, even Dark Knights despite how similar they play to warrior (outside their bursts) get more punishment when messing up.
I personally feel that this one job in the game needs a nerf on sustain, maybe then they would finally boost its damage, because if they did with how it is right now, it would be broken on the eyes of everyone, and not just some as it is now.

I'd like to know if someone disagrees with it, because it has become an unspoken rule all over the game, if there's a warrior, they are the main tank, and that has become a thing just because of its design (this of course doesn't mean the other tanks can't main tank, they totally can, I have done it and so many others, but it's always a better choice to leave a warrior do it because of their kit).
