But anywho, what I meant was I didn't want a territory in Athens that isn't already a border to become a border. Meaning, Tinos already borders with Kyklades and Euboea already borders with Thessaly and Locris, so i'd want to make one of them the link to Xios. Skyros doesn't border any other continents. So, hypothetically, if you were playing and you were trying to hold Athens, you would need to fortify Corinth, Boetia, Euboea and Tinos. I wouldn't want to make it harder still to control and connect Skyros to another continent, cause then you'd had to split your armies even more to control Athens.
Now I understand. I guess, then, that Xios to Euboea is the best to cut down on the circular nature of the map. With that link a player can go from Sterea Ellada (or Peloponesos) to Asia Minor much more reasonably.
