They were talking about fleet starbases quite a while back, but they never materilized. It would be good to have a dedicated fleet area. However, they shouildn't be free or available to just any fleet. There are currently a lot of 1 player fleets running around. (Person gathers 5 people, creates the fleet, then drops the unnecessary people)
A fleet should have a certain size to qualify for a starbase. I suggest 250 players (players not toons) If every current fleet has a starbase, there will be more starbases than stars in the galaxy.
