Would love to see the main form of progression through the game move away from grinding parties and leves (both solo and party). I think leves could find a place in the game as secondary content (almost where they are now they just seem more prominent because there still isn't a lot to do)

Party or solo there has got to be a better way to experience and progress through the game. Most games use quest after quest after quest. Its been done to death and while I personally feel its better than the progression we currently have I don't think there is a game out there that has really made such a great questing system that I'd just want it copied into FF14.

I think what many of us are looking for is a way to experience the game world actively (without a wall of text) in the form of adventure and exploration. Siobu's Eorzean redesign thread talked about this a lot. Grinding in a party will get you levels but certainly doesn't expose the player to much beyond the scenery.

A new variation on progression through questing (the idea being that its more fun and deeper than other systems) or something else. As Ventus said, brainstorming sounds good.
