OK...I come from EQ where rare items cost a lot just because of being rare, and not the stats. Is that the case for the Staff of Jordan?
First this staff is bind on equip, so it can be sold. Which is impressive. But the stats do not appear to be worth the 250gold to 300 gold I see it sell for. Yes it is a purple epic weapon....BUT would anyone pay 250 gold just to have a epic weapon to brag about, even if it is inferior to weapons that cost 10 gold?
What is your experience in WoW with item pricing. Why pay sky rocket prices for an epic weapon just because it is epic, it is not like rare coins or art that increase in price over the years.
What's the deal with this staff?

For a level 35 twink it is a great item.

Yea. Like smartidiot mentioned, this is probably one of the best 30-39 spellcaster twink weapons available.

If you plan just leveling out don't even bother. Heck, if that dropped for me, I would sell it unless I was going to make a twink in that bracket in the future.

It's also a bit of an in-joke item, referencing the "Stone of Jordan" which was a rare item that became the default currency when the monetary system broke down in online Diablo.
