Cabalabob gets it. They're actually moving away from homogenization with this. Now every tank can decide when and what to take to perform their baseline capabilities, and the devs can design the rest of each job to their heart's content because they'll all have the same necessities.

The difference now will be on each job's individual playstyle and core mechanics, not on which tank can actually outperform the other depending on the fight, which is in my opinion a far worse design choice than what we'll get in Stormblood.

This is a great change and it's really sad that people don't realize the goal of this. Hell, thanks to not having to carry most of the baseline tank skills (like Provoke, Silence, Rampart, Convalescence...) PLD is finally gonna have job mechanics. It will FINALLY have an identity with the new MP management burst and being the only tank with cast times and knightly party mitigation. WAR's entire shtick is managing your Inner Beast gauge in order to be able to Fell Cleave for literal days, which will fit the job's concept of going all out and berserk. Sadly, there's not much info on DRK yet, but at least we know it's gonna be all about managing your Edge Gauge. I'm sure they've come up with some interesting identity for DRK now.
