If you are following Pantheon: Rise of the Fallen, then you'll definitely want to check out Brad McQuaid's Q&A on Reddit yesterday.
Here are some of the questions:
User malakie00: How will you help the players find out which areas/dungeons have other players wanting to group?
Brad McQuaid: Blowing through content legitimately is part of the game. Power leveling by killing the same mob over and over again will be difficult. You don't level JUST by earning exp in this game. More on the Achievement System later.
User treestick: What aspects of an MMO do you find make it most immersive and feel like a world rather than a game?
Brad McQuaid: Immersive to me is an open world, grouping with others, a massive world to explore, and very different zones. Memorable encounters, barely surviving combat and talking about it later with my friends. A true sense of accomplishment. I could go on and on :)
