Even if SE were to double our inventory tomorrow, I'm fairly certain that most of the people who whine about lack of space will simply fill that up with more junk and come back to whine some more. I craft, I gather, and I'm in the gradual process of leveling all of my combat classes. I have four retainers and zero issues with inventory because I do monthly purges and get rid of stuff that I can easily reobtain should I want it.
