Now I know this has probably been suggested already, but I would REALLY like to see an Auction House implemented. I don't think it would be any harder to code then the bounty code currently in place, you could simply add an item to the Auction House at a fee, and asign the price you wish the minimum bid to start at. Maybe have a buyout option or what not. Winner recieves item in a small bag and winner gets gold in a small bag as well. Just like a bounty.
Auction House
It will be too open for abuse.
Please state why. Comments like that won't help do anything. You say why and I'll refute it. You mean giving a way for you to buy things with your other characters, well I say no, because it's just the same with bounty abuse, which is watched.
yes you could just log the ip's of the auctions and have a huge guard standing in the room -> ip match between buyer and seller -> guard getting VERY unhappy.
There already is an auction channel in game.
An auction house would become a way to save and trade eq between players.
I think its a great idea, but at the same time I am sure some arseholes will abuse it, too bad. Also, some drow cleric auctions a nice armor in this house, I am sure he does not want that elven paladin to buy it - at any price.
Just out or curiosity, does auction act like yell? Only ppl in the same area can hear?
Well, I see it as a positive thing. Rares don't have to be killed for, money can already be deposited into other peopls accounts anyway, and spamming on the auction house is annoying for everyone.
Eshaine and I have discussed the idea of a Syndicate auction house some time ago, so we HAVE thought and considered this as well. Personally, I think it would be pretty kickin' cool.
I think Festy likes WoW alot. 
And I like it. I think it would really tight.
I like the idea too, as long as there's a system to stop people giving their lower chars uber eq.
Great idea, only downfall I see is that you won't have to many people buying high end rares(deso/gear) with gold. The only big 'sells' I've seen in game have been trading equipment, not really buying. There's really not that big of a demand for gold at 50 unless you are an uncaballed melee class. And even then you can get what you need without buying it. Dunno, just my thoughts.
Honestly, I don't see a need for this at the moment. High end rares/uniques are intended to be gotten via PK or going to the actual location for a reason.
