Yes, inventory management is a part of every MMO, but so is giving players tools to do that management. I don't really find the dev's tired refrain about data storage/transfer very compelling - it feels like incompetence. The personal inventories, retainers, mail, and company chest of this game are all clunky, inefficient, and inadequate when compared to other games. That's just...a fact as far as I see it. Organized players can mitigate some of the impact of these poorly-implemented features, but not all of it.
