Perfect(my opinion) if anything would ever be changed, but I doubt the zones will change but this stuff is just made up.
Lv45-59 - Ardream (new map would be cool)
Lv60-69 - Colony Zone (same stuff)
Lv70-80 - New Zone (better and bigger boss's spread everywhere, more nation pts gained, more things)
Bifrost would be connected to both pk zones, not two seperate bf's and the monuments would be a little weaker.
My money is on having no change at all with any zones/levels.
