[@ClocktowerEchos] [@mattmanganon] It also bears mentioning: controlling two Primarchs effectively doubles the personal power at their command. Not the power they get from controlling a Legion of superhumans, obviously, but unless you actively have one fall to Chaos along with a good chunk of their Legion, they're never really going to fight against one another seriously, thus providing them essentially doubled strength when fighting a major enemy champion. Say, another Primarch. Just a thought.
