I can understand that the dev would prefer auction house option rather then straight up player shops/stall...
With the tax% in auction house it will serve to drain some gold from the server economy...
Don't get me wrong, I do buy plats...
Make player shops available in this game... And designate tavern as the only place you will be able to set up shop and afk without being kicked out... With player shops, ppl can sell and buy items, tavern will be full of players checking out items for sale... Player shops are kinda essential to mmor...
