I saw one of these the other day from a battle here also. I forget what force it was (thinking Ronin).
Also, glad to see that I am not the only one losing to 990+ lots. :3
No-one uses the equipment because the shell is so rare, no because it's crap equipment. If that was the case as Dasva implies, then it wouldn't carry such a high price tag.
This shell has been very rare for a very long time. But now that they have added it to the Campaign union caskets, it is beecoming a bit more common. I was fortunate enough to obtain one of these about a week ago and had someone synth the {Igqira Huaraches} for me. Second pair ever to touch the AH on sylph. Good luck to all.
