I usually leave one character slot unused, however here I have 8 characters, the last one I created (the prettiest) is "working" as storage alt. I don't want to delete it
The others have the materials for their respective professions. All of them have 2 bag upgrades and between 20-30 horse bag upgrades.
As I said in other thread, the character slots are not an inventory extension per se. The fact that many players need to use them to do crafting proves that the inventory system was not properly calculated for this game.
I did finally succumb and make a storage alt for all the armor/weapons I'm saving to research. Course this is my own damn fault for wanting to research EVERYTHING eventually, so I'm saving all traits on all weapons and armor. I'm actually not missing very many from my collection at this point. Course it'll be a year before I've actually learned everything but whatever!
