So, I'll keep this simple. Are you listening, Yoshi-P?
1. Hamlet Defense
Make sure you include Falcon's Nest and Owl's Nest in that new feature - I've always loved Coerthas over all the other regions, especially with Ishgard in the distance. I want to be as close to Ishgard as I can be, sometimes to the point of defiling the holy city just for the heck of it.
2. Gear Options
You give us dyeing options now, but where's the vanity option for wearing whatever we damn well please over our usual battle armor? I want to wear my plate armor as a LNC! I've never had any real appreciation for chain armor. (On top of that, I'm sure dated armor is not dye-able, so I can't turn my Dated Iron Gauntlets into Dated Iron Gauntlets (Red), eh?)
3. Go f*cknut loco on the features. Try to make FFXIV more like a sandbox MMO than a linear MMO.
If you have plans to give us our own housing, make it possible in 2.0 for us to decorate our house however we please, just like in Star Wars Galaxies! Want to mount your favorite spiritbonded lance instead of materiaing it? Put it on the floor, target it, use the X, Y, Z movement command (/move x 100; /move y 100, etc), to put it up on the wall. And so on.
