I'd want it to essentially stay the same and just have new zones added. right now the zones are really creative if you go to the higher level areas. Maybe if they made these alternate camps and then merged servers so there were a lot more players or something.

Like the northern zone in thanlana has all the cool powerplant type smokestacks. And then nine ivies in gridania has the awesome floating rocks where they sylphs are, and then if you go to emerald moss the area north of lasthold and the lake around alder springs are cool. Basically there are a lot of cool places in zones, they just either get unused of have high level mobs. So basically i think they should be useable :]
