Perhaps I'm overly jaded from ground PvP... but the matchmaking problem in GSF could be much worse than it is (for all that I gripe about it, myself). It's also, in some ways a good problem to have. Having large teams packed with veterans is fun while it lasts, but not particularly sustainable or promising for the module's long-term health. Having less experienced pilots diluting the pool also gives veterans good opportunities to...
Change ships to weaker builds and maintain some level of challenge. Teach the less experienced crowd. Take a breather from the more intense matches. Switch factions to re-balance the queue.
The problem is, after all, what we make of it. For myself - being obliged to queue mainly at off-peak hours (server time) - population is a much greater concern than the occasional mismatch.
On that note, a brief shout-out to Averann for choosing option 4 some weeks ago, resulting in about a 50 point game-to-game shift in deathmatch.... though that certainly proves Saevius' point to some degree.
