storage diversity is a weird way to put it? I also don't love your ideas tbh.

Frankly, I'd like Guild Wars 2's storage system.

There is a mat's inventory from anywhere you can right click your inventory "deposit collectibles" or something. This mats inventory can hold 250 of each material I believe.

There is a wardrobe system, so once you unlock a gear set you can just go to your wardrobe and select it to set it as your current glamour.

Then there is a dye system where you just unlock your colours and can dye galore. The best part? each item allows you to dye multiple parts of it so it's not 1 blanket colour.

There is a wallet that holds on to you all of your gold, dungeon tokens, and like 30 other things (https://wiki.guildwars2.com/wiki/Wallet)

Then you have your inventory and your bank which is shared account wide.
