We're suffocating on inventory space - how much of a priority is it to fix it?

[Nekodar]

The thing I find funny is they say that more inventory space can't be added (I mean, not even a little) yet what would happen if everyone suddenly bought an extra retainer? Obviously it's unrealistic, but it just proves that it's possible. I have one extra retainer and I'm still struggling with space. We really, really will need more soon.

Character inventory and retainer inventory is not handled the same way server side.
Retainer inventory is downloaded and synched from the server when you have the retainer up, but not otherwise.
Character inventory needs to be kept track of at all times.
