Future Of Dungeons, What Do You Want To See?

[Aeon]

Afaik Yoshida has announed those dungeons to be instanced, which wouldn't be a big problem for me, as long as you'd still be able to meet other players in that instance. I'd not like to see them all beeing "closed instances" where you'd only be able to see yourself and/or your group u entered the dungeon with, like Toto-Rak and Dzemael right now.
In all other MMOs I've been playing (including FFXI), I really loved to just move out to a dungeon, maybe into something like an "open instance", ending up meeting some foreign people who maybe share the same goals as me and grouping up with them, maybe even finding new friends this way. Good example for that in FFXIV would be the lately integrated LVL15 dungeon at La Noscea (sorry, don't have the english name) where i met some interesting people.
I'd really be sad if i could never ever meet anyone in all those dungeons I've already entered, cause i always found that to be really a lot of fun. What do you guys think?
Just my 2 cents and sorry for my english.
