Well, if you mean ALL as in every single vendor on the server, that'd be too much of a hassle, but if you mean every vendor in Roumen, I think its a good idea.

Sure it would be laggy, but, it was laggy before the market place. It would also make it easier for people to find the things they want, they wouldn't have to run all around town, just in a circle. It isn't too difficult to get to, the only thing that was annoying about getting around Roumen was clicking on the houses.
