I haven't played too much GW2 and only a long ago. But god i actually enjoyed AHing there. I should make more money because i have some goals with gold in this game, but i don't do any AH because it just feels bad and i hate the UI. A worldwide AH with automatic 1 bronze less prices if you want to sell someting, it really felt like there is a real demand-supply market in the game (also the fact that i don't have to click 200 times if i want to buy 200 of something if it's the cheapest in the 1 item stack size). I get it that some people has no problem with the current AH system in the game, but i think they just didn't see any better one and got used to it during the years.
