"If you ignore them long enough.."

I would also like to know where the following concepts are:

-The ability to enter dungeons with NPCs
-The ability to have companions other than our chocobos
-The possibility of using retainers as companions inside and/or outside of dungeons

Having NPC partners was mentioned by the devs as a possibility some time ago, but it has gotten little to no coverage since.

those introduced would directly signal the death of the game. NPC companions in MMOs (especially for instances) only get added when there's not enough population anymore.
