I still can't summon a retainer in uldah! Just because you can search in Grid and Limsa now doesn't mean anyone is actually GOING to! and by no means does anyone want to travel to Limsa or Grid to check their retainer. SE you need to scrap the whole idea of market wards and implement an Auction House. If you cannot because of 1.0 limitations then the least you could do is limit people to 1 retainer selling things per city so everyone has a chance.

-ps The whole premise behind the market wards is absolutely ridiculous. Where in the real world are you gonna see hundreds of ZOMBIES bunched together selling items, never moving, just standing around 24/7?
