A thing that would make the paragon easier to use is if it would also generate mass and energy for teammates of the paragon-owner. Then you don't have to do stuff like gift units to get the unit cap down, or gift mexes because they stop working when you have a paragon, or gift factories so the paragon-owner can produce out of them. It would make having a paragon more useful and make it easier for players to cooperate to spend the mass.
This would also mean that a paragon is more useful if you have more teammates alive. So there would be a benefit to staying alive.
