The biggest problem from my point of view are useless equipement templates, which cannot be saved and I need to destroy every one whenever I want to move my account bound equipement to other character. I don't really care about saved inventory slots, as this is not QoL really. With ArcDPS I was able to unequip items, move them to another character, them move them back and load whole build with all the items in place when they were in my inventory. Now this is completely not possible.
