Blm also sorta has the tools... unfortunately it's tied to AM/AM2 which still have ridiculous cast/recast times and insanely horrible dmg/mp ratios so it's not really feasible to actually use them. Douse is great but waaaaaaaaaay too long of a recast.
Pup and bst also have tools in the form of transferring the hate to throw away pets (though for bst slightly less throw away due to timers) but good luck getting any no pet group to take either lol.
smn gets that new bp that takes 25% of enmity... but given even mediocre DDs like those pet jobs can go from nothing to capped a couple times a minute anything less than full enmity loss/transfer isn't really great anymore (other than for rng pts). So the only current work around is greatly lowering generation but really only rng can do that since they possess the only rapidly repeatable way of effectively going beyond the -enmity gear cap and only because they can go all the way to zero. Even if they raised the -enmity gear cap to 90 (and put it on a bunch more gear or something) it still wouldn't help on high hp mobs
Should also be noted that those with strong magical ws if there pt sets up for it achieve something similar to the ranged relics with relatively low enmity for the dmg ws... but your melee dps will override that just like rngs shots will when decoy is down though not quite as bad I think because attack speed differences between shooting and meleeing which is what ends up determining who has mob attention when everyone is capped
