I don't see enough talk about this, but there are so many good locations in the game that can't be visited by multiple people! (i.e. Terncliff, the Omphalos, Redbill HQ, Prima Vista, Elysion etc.) Other locations similar to these though such as the Empty, the Royal Menagerie and Lyhe Mheg are open for multiple characters to visit at once.

I find it odd that so many of these locations are locked to solo instances only, and I think having the option to visit them with at least other party members after completing their stories would be fantastic as a little hangout spot or for roleplay and GPosing.

Is there any chance Square could go back to adjust some of these locations if enough attention is given? I'd hate to leave all those unique areas to waste other than the occasional solo trip or quest which might take you back there.
