I personally hope there is a traits overhaul in the future. Traits are horribly out of balance. Dstahl once said that he hoped to figure out a method to make ground traits more desirable, because everyone is only picking space skills.
And lets not even get into the entire efficient trait for the Saurian BOs. And the story that people are farming the lower levels to get lucky and get a Efficient Saurian BO which they can turn around and sell for 20 to 30 million EC.
Ground traits are the only ones that matter, unless of course you are only going to do space missions.
