you mentioned it in the first post, but perhaps you can find a solution anyways, i am speaking of the not very good to see location names inside the area of influence. So having a different css font-family, which has a better contrast through outer lines incapsulated(not quite sure if that is the fitting word) in the font-family could help or having also white as color for the location names as by the area effect it should be clear that something has been taken there. If not white then perhaps a light/bright grey.
EDIT: or give a light/grey background for the location names(div/span container? are these still been used with all the new fancy css versions? rounded css edges), that way the text color could still be that of the faction who owns it.
