In my opinion one of the things that detracts from enjoying your AO experience is unnecessary time sinks. And while shop terminal camping may not be the biggest time sink it can certainly be very annoying when you are left to run from city to city trying to find a certain item at a certain quality. I have spent hours of my in game life running around looking for certain weapons, armor, ts materials, ncus, etc for any number of purposes.
In order to fix this i propose that most terminals be changed from the inventory based system that is in place to a drop down menu that allows players to manually select what item they want, what quality they want the items to be, and the amount of the item they want. Perhaps there could still be a way to check stats on the items and have a visual reference for them so that new players could still navigate through them without the need to reference third part utilities/web sites.
Admittedly this isn't the most important fix that can be made to AO game mechanics, but it is something that can allow players to spend less time running in circles and more time playing the game.
THIS ISN'T ABOUT ADDING ANYTHING THAT IS NOT IN THE SHOP TO THE SHOPS. ITS ABOUT HAVING ALL ITEMS IN THE QL RANGES THAT ALREADY EXIST IN SHOPS AVAILABLE ALL THE TIME.
