This thread again.
I've always argued for having an auction house since day one. The biggest reason why? Sure the wards are a very crude form of an auction house, that "somewhat" works at the moment.
What happens when ps3 is released? Or if the game for some reason gets somewhat popular?
The small number of people with a few retainers right now have already caused problems for the wards since release. Fill the servers up, give each player a few retainers, and then what?
Overcrowded crashing wards. Imagine going into say the lower tailors row. There's 20,000 retainers in there. Only about 20 of them load a time, if you have a super nice pc. I mean, seriously? lol
The AH needs to happen, hands down. To say "the wards are fine" is just a temp fix IMO, translated into "for now, I'd rather they worked on other things, but the AH NEEDS to happen sometime in the future".
If people want something unique, maybe try making an auction house that is cross servers. I think that would be neat.
