Oh, I was thinking this was the map with 4 islands (one in each corner) that's a 5 x 5. There is a map where the 4 islands extend all the way down to each corner. The water is like a big "+" sign across the center. I can't think of any other way to describe it.
Anyway...Paradise (now that I can picture the map) is another one were Aeon has such an advantage. When the islands are small you don't have much room to build, and you don't have much mass. It costs a lot less for Aeon to build T1 tanks then it does for EUF or Cybran to build naval units or T2 tanks to bring the fight to the opponents shore.
Now I'm curious what the name of that other map is...I'll have to look it up tonight.
