Like many other players I prefer to be out in the world adventuring to walking around cities doing busy work. Sadly, ESO forces me to spend close to half my game time doing the latter due to the incredible mismatch between the rapidity of loot acquisition and available inventory space.
This problem breaks down into two parts. The first is that player inventory space fills up with loot too fast in normal play. The biggest cause of this is the massive number of different crafting materials a player acquires. Provisioning is the worst trade in this respect. Some players would suggest being more selective in what you loot, but this is time consuming in itself as it requires judging the value of loot against your current inventory each time you loot a corpse or container. That also means spending a huge amount of time researching the value of thousands upon thousands of items that one comes across. Almost nobody wants to play the game that way. They want to loot everything and then sort it later.
The second part of the inventory management issue is the amount of time players spend clearing out space in their primary inventory such that they may get back to adventuring. The easiest method to open up base inventory slots would be to dump a day's loot into storage for sorting at a later time. However, bank space is massively, and I do mean massively, inadequate. This means that you cannot batch process so to speak. Each time you come back to town you have to sell, craft, or destroy or you cannot keep playing. Want to go do a group dungeon tonight? Too bad. You have to spend the better part of an hour organizing your inventory and you won't have enough time left after that.
And the process of doing this isn't exactly streamlined. Even with UI mods, selling your loot to other players is a serious pain in the rear end. Determining a fair price is hard with the fragmented market ZOS has created with their guild store system. If you want to get access to a larger market you have to spend even more time spamming the zone chat with WTS messages.
The bottom line is that inventory management in ESO is a clear quality of life issue that will dramatically increase the likelihood of a player deciding to leave ESO for greener pastures. ZOS cannot justify the amount of time and effort they demand that players spend on arranging their loot in this game. It is time for a change.
