yeah hopefully right? How likely is that now with the new expansion? I would expect the prices of all of the old AHable gear to come down quite a bit. And its not like he bought it for a valid reason, I mean, abyssea? He could walk in there wearing a Kirin's Osode and achieve the same results in the same amount of time. Its abyssea.
Eh, I dunno that Ocelomeh body will take that much of a dive. There's not much in the way of easily obtained DEX body alternatives from the new content, so there's still a market for jobs that have DEX mod suff (Shijin MNK/PUP, Shun NIN, Jishnu RNG, etc). And don't underestimate people who don't know better grabbing while leveling their shiny new RUN, I've noticed a lot of light DD gear at all levels increasing at least for the short term.
In fact, on my server Oce body has only gone UP over the past month, including post-expansion once people started seeing stats on new gear (causing some other stuff to take a dive right away, Brego Gloves for instance). There's always a risk the market for one item will tank if a new option is introduced, but I'm usually not that worried about spending some gil on a temporary piece when you can sell it back. The sooner you sell it back, the better chance you'll get about the same amount you paid for it.
Not that I disagree with your point that it probably doesn't matter if you're just doing Abyssea to get something like Loki/Tantra (for that purpose you'd be fine tossing on Osode or Aurore really). But if you've got the spare gil, eh, It's a pretty good AH piece.
