Just a little input - a ton of games that have these kind of 'command points' (aka super meter) have recognised that it's good to give points to players that get in on action.
In fact, it can often be much better than giving points to players that build 'point creation' buildings - since that just rewards turtle/eco play, which is already rewarded with mass and energy.
Have you given much thought to a system akin to :
Units dying give x% of their mass cost to the player that destroyed them
Units dying give 80% of the above x%, to the player that lost them.
?
This tends to be roughly the format that games like Dawn of War 2 use, and it tends to work nicely as a way of encouraging players to 'get stuck in' in big team games.
Just some thoughts. Nice work on the mod!
