I would like to see in-game lobbies for clans (like in StarCraft 2.) Also maybe have a clan wars type mode, like in the campaign, where different clans could sign up for weekly matches in which you fight over different areas on Mars. The clan with the most areas controlled wins the weekly match and maybe get some in game items. You could also use the winners to be in some kind of bi-monthly seasonal, in which the winners after, lets say, 8 weeks of games, come together and do a best of 7 game. The clan that wins these could then go into a annual game. This would create a in-game competitive circuit, which would help standardize the meta as well as make the game more competitive, thus making it easier for you folks at Mohawk to sell units.
I included a imgur link of a mock up of how the circuit might work
