What about game balancing in MP?
Even if the sides aren’t so technically different, balancing in MP proves to be a challenge. Each army should have weak points and strengths. Even more so for the ‘Green’ army (Beta leak). We still think that all sides should be distinguishable yet balanced. In the end, people should be able to come up with interesting strategies for getting the best equipment mix for each side in a MP fight – if we do our work correctly.

Seems at last they are thinking about MP games, it’s not something they seemed to be bothered about in the past.
