Hi, I play XIV (critically acclaimed, free trial, level 60, award winning expansion pack Heavensward, you know the meme), allow me to infodump on you lmao
Buffs are a thing in XIV, but their cooldown is usually longer than their duration, so they form your "burst phase" - when you use all your buffs and most powerful attacks at once. (This is important because one job, the Ninja, has a move that makes the enemy take more damage for a few seconds, so everyone wants their burst phase to line up with their Ninja's Trick Attack.) Most jobs have just a few buffs, and most of them apply to the user only. There's no "buffing jobs" - if you're in combat, your goal is to kill the enemy, and that means dealing damage. If you have a buff, it's part of your damage rotation. Square-Enix does their best to balance the game so every combat job is viable in its role, and they usually do a good job of this. Even when everyone can agree that this or that job is the "worst", it's still good enough - even at the bleeding edge, like world-first raiders, a "bad" job that you play well is always better than a "good" job you play badly.
Crafters, gatherers, housing, gardening, pets, and lore are all valued parts of the game, and there's not really anything that "nobody cares" about. (Except for Verminion.) But they're very much separate from combat.
I'm vaguely aware that things worked differently in older MMOs, like Everquest, but modern MMOs are... streamlined, would be the nice way to put it. (The mean way would be "dumbed down".)
