Would Bards and Machinists make good use of Diversion?

[zuzu-bq]

All other jobs have access to Diversion, and casters have Diversion AND Lucid—one queller and one dump. BRD/MCH has no queller. Enmity quellers and enmity dumps act completely different from one another.

In order for aggro to be dumped, you have to build it first. When you’re quelling enmity, you’re quelling how much builds up. BRD and MCH can manage 9 to 10k bursts in their openers. A queller would benefit them far more than a dump.

You don't get it. By your logic you'll be adding a third enmity ability to Physical Rangeds making them the only role with 3 abilities for it. So far the only DPS with that is NIN because it's part of their support toolset. Also by your reasoning of "they're one of the burstiest" Warriors should also have diversion. And that ain't happening. Casters have those two Skills and only one of them use both. RDM actually would be able to live without Lucid if their rotation wasn't MP negative without it. SMN rarely ever needs enmity control and BLM can easily live without Diversion.

Also you're underestimating the power of literally cutting your enmity in half. WHM and AST are jobs that generate ridiculous amounts of enmity if they so desire and they only have one, meanwhile BRD and MCH have two. If you're having problems with enmity either your tanks are slacking or you are. What it's needed in this situation isn't a new crutch. It's playing better.
