If we're going to do a continental map, I would suggest removing the rotating geowarps and fixing them in place, bring back old Oshur using this lattice setup:
In this setup, all continent links can be easily rotated, you have three home continents and campaigning is easy. Events could be done by linking one of the home continent links to one of the battle islands and removing the other three from the lattice for a short time.
As I recall, everyone liked it back then, even Beady was considering implementing it before he left SOE.
