To tap in to that quote, It isn’t possible for us to boost inventories much, if at all, but what might be possible is converting items that aren’t customisable (such as hats, frames, skins) in to different buckets in the backend service, like we did for illusions.
Sure, deeds aren’t customisable from the front end, but they are “custom” items, which is why those will likely remain unchanged until a time comes where we look at the system as a whole.
