The Ground Skills will hopefully come soon, but it's likely doubtful they'll hit before the early launch in December. They should be here before the actual F2P launch... at least it would make the most sense.
I'm going to have to disagree with you. Making the most sense would have been rolling out the space and ground skills revamp together so that they could properly be tested and balanced. Instead we only have a half the picture. How can I test and balance one half with out seeing what the other half looks like?
