Continuing on the inventory tangent, I'd like to point out a couple of things people routinely seem to overlook, misunderstand, or have biased opinions about.

(1) There is absolutely no space problem. I level every DoH / DoL job concurrently while maintaining three combat classes (albeit only one at level 70) and a Glamour set for my main; I have oodles of inventory space and Retainer space. Does that mean nobody has inventory issues? Of course not - but it does mean that inventory issues generally arise from "pathological" use cases where people are utilizing far more space than is necessary / intended for general play. That's the metric by which SE is going to assess space, and it's the one we should keep in mind.

(2) There IS an inventory management problem, which is what I think SE should really focus on fixing. Consider a few of the glaring lacks below:
  • No robust tools for sorting or finding specific items within one's inventory.
  • Too many currency-style items (Gysahl greens, Dark Matter, Glamour Prisms, Beast Tribe currencies, Tokens from more or less any Raid / EX Primal, etc.) that do not get assigned to a currency tab of some sort.
  • Unnecessary splitting of various items, such as Dark Matter being tiered or Glamour Prisms being broken out by DoH class.
  • Clumsy item retrieval for quest turn-ins (Key Items, in particular, should be completely automatic).
  • Lack of a Glamour log (and, yes, for a game that already had Log-style setups for Crafting / Gathering / pre-50 Hunts, this was absolutely inexcusable).
  • A pathetically poor implementation of the Armoire, which encourages people to mix items they might actually use with items they just want to hang on to for fear of not being able to acquire them again.
There are surely other problems as well; these were just off the top of my head. All of these, viewed properly, are inventory management issues, not inventory space issues. Addressing them would certainly free up some inventory space, but primarily it would make FFXIV more playable and accessible - a result that is far more likely to draw attention from the development team. On the other hand, treating them as space issues and doubling or tripling our inventory space wouldn't improve XIV's playability at all; it would arguably make it worse. Simply keeping track of all the space we had, were we to use most of it, would be a nightmare.

Unfortunately, based on the LIVE Letter (to draw back to the original topic), it would seem that SE has no designs on really solving these issues. The general feel I got from the entire thing is that, aside from a few job tweaks, the dev team seems content with the state of the game. In my opinion, that is a troubling sign, one that is almost certainly going to cause me to cancel my subscription as soon as my girlfriend loses interest in the game. But, to each their own; I can't speak for anyone but myself here.
