I still strongly favor the method of backseat coming. In that for marines one actual player is calling the strats from the ground and the com executing the plan. This frees up apm of the com to focus on implementing the strategy and predetermined build rather than trying to fly around the map and get data as to what the current state of the team is and where they need to be to win the game.

It is easier for those"on the ground" to see how well they are doing in particular areas of the map and where they can best gain strategic advantages. As the game matures and particular per hive builds/rushes are developed it will be easier for more people to com by first following the predefined recommend build for those conditions and then branching out from there.

I would com more but as I am usually one of the best shooters on the team I find it more valuable to have someone else com and then just get the team to implement a predefined build/hold pattern for that map/hive location.
