I understand they're trying to limit the amount of crafting through very limited inventory, but having a bank that is the same size of your personal inventory that is shared across all your characters is far too small. I have ~20 CE treasure maps and several vanity pets that are taking up space. They either need to increase the base personal bank size, reduce the cost to upgrade, or come up with a way to manage vanity pets and extra items like treasure maps that doesn't involve inventory. I don't want to need to spend the majority of my gameplay managing storage space.
