I've played a coulpe of games with 1.1 now and found the Torian's to have become the race to beat in a large/huge game with lots of planets to settle. The 30% growth is just over powering for claiming new worlds now. This was on inteligent also and I had no chance to see the new human or Drengin AI's. They just got crushed!
Anyhow it looks to me like the growth bonus is just over powered on this type of map.
