I think the TP would be a much more pleasurable experience if on the main page there were two prices for each item, the current best buyer and seller price, and beside each was a checkbox or button that let you pick one or the other. And then one Sell button that sells everything you have selected in one go.
So, imagine you are selling your stuff. You look down the list, choosing which price you want for each item. You click on either the buyer or seller price.. whatever suits you. You don’t go into the item page unless you want to check out the other prices or stock, sell multiple items, etc. but it certainly should still exist, just not be forced into it.
For me personally, I am very lazy indeed.. and I like to just sell my stuff for the buy price (unless it’s a stupidly different sum). This change would cut down on my amount of clicks by at least 3×.. and the time spent would be waaaay less. Let’s face it.. selling your stuff isn’t exactly fun.. and if you’re as unlucky as me to have kinda crappy internet – the TP is not so smooth and quick as it might feel in the Arenanet testing lounge
