Storage is always at a premium in Guild Wars 2, especially if you’re handling multiple characters who are all squabbling over the same shared bank space. The good news is that ArenaNet seems willing to work to expand one of its storage systems to include more types of items and is reaching out to the community for suggestions.
“I have said that we would look into the material storage system to determine if we could reduce the current restrictions on what is allowed to be deposited there,” Game Designer Linsey Murdock posted on the forums. “We have completed that investigation and are ready to talk about what all of you wish could be deposited into storage that currently cannot be.”
Murdock did preemptively cut off some avenues of discussion, including nominating crafting components, keys, and pure salvageables. “I totally understand how much folks want this (my shared inventory slots are largely taken up by keys, so I get it!) but putting keys into material storage is not a viable way for you to get a key ring. Sorry,” Murdock said.
