At certain points being able to clone yourself and choose an alternate profession -or in this case faction- with the cloned character
Can't see it happening though, this games easy enough to grind as is. If it did happen I'd be more expecting to see new Romulan players start off as say Lt Commander 6 (like Klingons starting at lt 6) and then Cardies if they happened at Commander 6.
Scramble sensors isn't awful as long as you pay attention to U.S.S. or I.K.S.
But the klingball counters the fedball. It's just hard keeping the klingball together because disorganized rabble is common enough on the fed side that disorganized rabble on the klingon side can rely on cloaking to get a few kills and maintain the illusion of competence. Klinks almost always have to deal with one or two elite-ninja-assassins who think that it's a good idea to sneak up on the opposite side of the fedball from everyone else, 15 km from their healers (who are sticking with what's left of the klingball).
