All evidence however points to EA being the lead candidate for finesse fleet status.
Well.... In this case, the EA is the victim of an overall game balancing item that was mostly proposed and pushed by us, the players.
As Matt Sprange has mentioned, each fleet has their own individual play item that makes them different from the others. Minbari have Stealth, Narn have E-mines, and the Centauri have hordes of good lower level ships. The EA's gimmick was, and still is, fighters.
In the original printings it was pretty obvious that while the EA ships didn't match up pound for pound with ships from other fleets, they made up for it with hordes of fighters on their ships. It was fun to watch your opponent sweat over attacking the big ships or swatting the gnats and the battle for fighter superiority took up a big part of the game. Many people considered them the achilles heel of many fleets. Lose fighter superiority and you could be in for a rough ride. Then it all changed...
People sat down and came to the realization that due to the game mechanics it was much more effective to take a fleet made up purely of fighters than to bother with capital ships. The worst example of this was the 180 flights of Thunderbolts that an ISA player could field in a 5 point war level game. Why was this bad? First off, fighters move last so you get to watch your opponent manuever all his ships and then you swarm them at will. Secondly, when fighters were nominated to fire, they all fired at the same time. This meant that the ISA player got to roll nearly 900 AD without an answering shot from the oppossing player. Finally, the old rules of 6-5 and 6-6 insta-death criticals were around. Nothing more frustrating than watching your pristine Bin'Tak/Warlock/Octurion get taken out by a single hit from a Thunderbolt's gatling cannon.
For these, and other reasons a change was demanded of how fighters work. They were too strong and had to be stopped! Mongoose dutifully listened to our feedback and begin tweaking the rules. With SFoS, they suceeeded in making fighters no longer the single most powerful thing in the game. Wing sizes were reduced, stats were lessened, fighters were forced to fire after all capital ships, precise was removed and insta-death criticals were no longer possible.
Trouble is, all this tweaking effectively gutted the strong point of the EA.
