Would Bards and Machinists make good use of Diversion?

And that's why Invigorate still exists. Although you're not entirely wrong, outside of that saying the melee is being punished by dying past Tactician is bad well, yes it is. But again they died, if death had no punishment in the game no one would care about dying. There has to be punishments to deaths to incentivise players on avoiding it.

Paladin and Dark Knight wish they had access to that. Even Warrior only gets 200 TP from Equilibrium. Death has a punishment, you suffer a 25% penalty towards all your stats except vitality; 50% if it happens within that 90 second interval. I can assure you whenever I die, TP is far less a concern than my damage plummeting. You really ought to stop using these comparisons. They're quite bad.

If Diversion would simply be better you wouldn't see BLMs running without it. Which they do, constantly. The example your provided only shows someone didn't slot Invigorate in a run with possibility of death and got hurt because of it. If you're progressing a fight or expect deaths to happen you should slot the skills to play around it.

First and foremost, most optimal Caster guides suggest both, though put more emphasis on at least having one. Second, casters generate much higher sustained enmity than ranged whereas the latter only needs aggro cuts in their opener. Basically, it boils down to Diversion is more useful to Bard and Machinist.
