Armoury, Retainer Inventory Space

I know this is a recurrent topic for every live letter, but are you working on a way to help with the obvious inventory space problem ? If you use all classes in the game, you have two open slots in the main hand armoury space, that is if you don't have PVP equipment.

This problem also concerns retainer inventories. I, like a lot of my fellow adventurers, collect primal and raid weapons as well as some equipment sets and I have two retainers full just with equipment and it doesn't seem right to have to pay for a second additional retainer to enjoy the game to its fullest.
