Enmity for Nins?

[Serial Rain]

I'm just wondering out of curiosity, but in your opinion, are the +Enmity Rings and Earrings worth the equipment slots for Ninjas? I've only seen one Ninja on my whole server that's above Lv. 60 that uses a +Enmity equipment. (Most use +Agi/Evade, and +Str/Dex equipments instead, as you might've expected.)

Enmity Equipments I know that nins can wear are;
Nemesis Earrings, Mermaid's Ring (?), Hades Earrings, Eris' Earrings, Fenrir's Cape.

Just want your opinion; thanks.

The level 64 gi-type armor has enmity pluses, and it seems very popular. I've seen a couple of ninjas at high-levels on Fairy with the other plus enmity gear, but the majority do not wear it, so I dunno.
