Is there a possible way to, except yourself, place enemy teams on specific planets, or are they all placed randomly? I play 5v5 and within 30 minutes in the game, my allies have already destroyed the entire enemy team. This game seems to lack a lot of features from the Supreme Commander series. :/
If you use a random system that you get from the lobby, then you will get random spawns on 1 or more planet (depends on the system size). In the system editor you can set which planets and how many planets you can spawn on, but you can't select where the spawn points will be. Furthermore, you cannot have a particular team spawn on a specific planet.
