Oh here we go.
That's not true at all.
All warrior has to do is, get all the things in front of him, spam OP and his job is done. Maim is needed to be optimal, but it's by no means a must because it is NOT a threat skill. Opening with Maim is like saying "herp derp don't mind me, I'm boosting my damage" while the rest of the party gets mauled. (don't confuse this with being killed, cause unless the healer is also inadequate, nobody's going to die in lower level content) If you have to for a single moment THINK about when to use wrath in trash then you are clearly overthinking it. There is no reason to save it.
DRK may have more to look out for, namely their MP, but their threat modifiers, damage, and darkside makes threat so trivial that you'd be bad for the sole fact that you WON'T use unmend/unleash/dark passenger and whatever. Pretend it's like dragoon if it rocks your boat. Just hit them all, and you can spam soul eater combos all you want.
PLD has the weakest threat modifiers AND weakest damage. You have to do more. Many are deluded that their barely decent job is good job when a lot of the time, the DPS is either clueless, incompetent, fumbling about, broken, or not good for that situation. And oh boy you're in for a rude wake up call when someone powerful AND competent enters the scene, especially when you get to 30 where most everyone got a massive power up and all you get is shield swipe and sword oath. So get ready to learn why your simple skills aren't working because the real difficulties is the system behind it, not simple controls. Geeze it's just like telling this to someone who thinks 2.0's tanking was the "bestest thing in FF14", even though they needed to be patch buffed the most times. It hasn't been a whole expansion before needing threat patches AGAIN! And man as much as peeps scream that this is the easiest class there sure are tons of players freaking out over MP. And how is constantly switching targets a simpler thing than using threat AoEs. . .? And oh geeze I "wonder" what silly junk you'll be writing. And I cannot count how many times where I came in as DPS and took over tanking.
Let's not forget what 3.0 did with the level sync. Making it harder on new jobs because now everyone is leveled down to high quality levels instead of normal, that means the better geared DPS are even stronger than before.
And I'm not going to bother with this type of comment again.
