To then finish this world, I want the random mini-instances like suggested here and here, popping up everywhere for the players to explore and find small treasures. And a Ring-system that allows us to make our own more permanent mini-instances and attach their entrances to for example the outposts we built in the no-mans-lands. (These Ring instances would be permanently available - loaded onto the server when someone enters and closed again when they're empty.)
Apart from that, I'd want more exploration anyways. I'd want some system of tracking down the randomised instances, I'd want amber cubes out in the world to be tracked down. I would want excellent and supreme materials to be treasures to be found, never in the same spot twice. Same with nameds and bosses. (Aggressive specimens might thus all have to be relocated to the no-mans-lands.)
