Server blablabla memory issue. I reckon SE needs to take care of that first, since alot of things are not possible, because of this issue:
- More inventory
- HUD changes
- Content like the Primals being in the open-world
- Character customization (this is why Au Ra can not swap horns)
- Probaly more stuff that SE had to scrap, because of the server memory thingy.

I dont know if this is, because of the PS3 or something else, but aslong as this issue is still there, we will never get a true FFXIV game and only the bare minimum.
