A71. I understand everyone’s request, but since additional inventory space would increase the data transmitted, there is a risk for server crashes, so this isn’t something we can do right away. We’re optimizing aspects with every patch, so we will continue to look into this for the future. Until then, we would like to add a feature that stores and retrieves whole gear sets to and from retainers, and make other quality-of-life changes to retainers.

A bit premature, I know. However, I can't help but be intrigued at the idea of storing gear sets on our retainers. Needless to say, I am looking forward to it. :)
