How could I not be drawn to this post?
What truely seems to be lost is that scouts are ONLY good against light armor. A good early game balanced fleet is scouts mixed with light frigs.
I cannot emphasize this enough. Scouts can be countered by just about anything that has medium armor and up. Skirmishers and flak will take a little bit longer to do the job (skirmishers are pathetically weak compared to their counterparts even with reintegration).
Bring out some fighters if your opponent is massing scouts, or even some of your own ( they counter themselves ). Fighters absolutely maul scouts. So he brings flak to counter the fighters? Make light frigs. Light frigs aren't the world's best counter to scouts, but they work. Also, try some turrets. Turrets absolutely screw scout rushes.
One arguement about scouts that I feel is truely lost is that you can make them from the beginning, so the fleet will be bigger provided you never stop making them. Yes Scouts are tough, but they do pathetic amounts of damage.
Scouts lose to:
Fighters ( no question, scouts can't destroy carriers for shit )
Other scouts
Light frigs ( Skirmishers need reintegration but otherwise all light frigs win )
Flak (so tough that scouts do almost nothing noticable )
HC's ( obviously )
Look. If you see massed scouts that means your opponent is being aggressive. You're going to need a big fleet too. Take a look at how big his fleet is and get a rough guess for how big it is in terms of ship slots and try to get one at least 3/4 the size (preferably equal in size). Honestly I'd like a look a replay or two where you say you've seen this happen to you.
I don't think scouts are imbalanced, however I think seekers could use a slight nerf (about -10% health), but other than that leave 'em alone.
Countering massed scouts never has and never will be hard imo. It's like any other strategy in the game. There are advantages, but there are also counters.
I'll admit I've never been on the recieving end of a scout army. Normally I'm the one using them.
