Not really, for the +3 enmity you can't find a more cost effective piece of gear. I don't know where everyone else's priority is at, but for me I have found in most situations Enmity is much more important than VIT.
to me this ring is only really good for the enmity
the latent is just a bonus
but +3 enmity u can't find more in a ring only sattva as the same amount of enmity
I'm not sure why Azulmagia has been rated down. Perhaps people can't read english. Azulmagia is absolutely right. The THRESHOLD for constant 2MP/tic is higher with Parade Gorget + Hercules Ring as PLD already gets 1/tic from trait. So from 0-50% you get 2/tic and from 75-100% you get 2/tic. That means you will have 2/tic for 75% of your healthbar.
This ring is a good macro piece for the enmity, toss it in with a blitz ring for flash, macro it in ur enmity set for cure/ja's. Not to mention it's only 30k (at least on my server) which is cheaper then the 60k~ you spend to get adaman to macro in for the same reasons, and adaman only adds 1 enmity over AF.
