DPS Enmity controls

[Bourne_Endeavor]

Using diversion also cost you one role action slot. You have to choose do you wanna use lucid for mana, swiftcast for mobility or instaraise, addle for aoe mitigation or dps, apoc for tank busters, manashift for healers or bard foe, surecast preventing kncokbacks etc. You dont really wanna use diversion and sacrifice one of these skills if it is not 100% demanded.

Players utilizing those skills typically know how to manage Lucid/Diversion enough where they don't need both. In dungeons, you will never need apoc or addle since those bosses barely tickle half the time. In full party settings, there is no scenario where forcing a tank into tank stance is a rDPS gain. In fact, it's an overall loss even if it means you lose a GCD. That's how bad tank stance is, and why tanks avoid it like the plague. Even with that all said, there isn't a fight where you wouldn't slot Diversion and/or Lucid. And you should time your Lucid uses around your aggro not your MP. In fact, it's far better to use Lucid when you're at 80% MP because it won't tick fast enough to cap, provided you're actively DPSing. The only two jobs who have any argument about not managing aggro are Bard and Machinist, because they have to be mindful of blowing a party resource. Samurai and Black Mage? No, they have options. And if you're to lazy to use them, well, the tank's patience determines if you live or not.

It also depends on class. SMN pet is doing big part of your dps and pet have separated enmity generation compared to your main character. So you theoretically do like 25% less enmity all of the time. Even for world first UwU kill summoner did not use diversion.

He did, however, use Lucid. Bear in mind, Ultimate is a poor example, especially WF prog. Everyone plays safe then because the objective is the first kill. You also have to consider each Primal and Ultima all have aggro resets. Therefore, the Warrior will always have an Unchained + Equilibrium opener ready. As the Primals are roughly three minute fights with multiple jump phases and adds in the case of Garuda and Ifrit, there isn't nearly the same aggro creep as you'd see in say, Demon Chadarnook. Not to mention, you have a Ninja rotating Shadewalker and Smokescreen.

Tanks in Ultimate aren't using tank stance for aggro reasons, they're using it live because stuff actually hurts. And you can't cheese mechanics like you can in Savage.
