I agree with mostly everything you discussed. FFXIV is a great game, but so much of its content is left barebones. I would love to see them go back and flesh out features, like what I hope is happening for Wolves Den in 3.2. Grand Companies are a feature that needs an overhaul.

Plus Besieged remains one of the most epic things I've ever done in an MMO. I would love to see something similar introduced in FFXIV.
