DPS Enmity controls

[Lilyth]

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.

While it's true that the SMN's is the only real exception here since their pet takes part of the aggro generation from the class, their opener is still quite bursty, easily spiking more than 10K DPS. Dealing with spiky openers is Diversion's main scope.

The world first UwU kill SMN not having diversion is a completely different and very specific scenario that shouldn't really be used as an excuse to not use it on, let's say, Phantom Train normal.
