The most egregious example was a CT run earlier.

Guy has a HQ i90 crafted belt. The i80 belt drops. He Needs.
- The belt is unsellable
- The belt is not Convertible to materia
- The belt cannot be used for Glamours
- The belt cannot be traded for GC Seals that I know of
- He didn't say he needed it for retainer
- He obviously wasn't using it, as it was strictly inferior to what he was wearing

He literally Needed ONLY for the sake of Needing, and outright said as much. One or more players could've put it to use now or in the future with that class. I got vote dismissed for calling him out on it.

That's the kind of behavior this causes. Greed, pettiness, hostility. Nothing good comes of this, it makes the game more antisocial, it makes players less cooperative, it discourages altruism and sharing.

It's a sad day when I have to point to the WOW community as being better and friendlier on a subject, but that is so when it comes to this.
