If one gets too insanely strong, it won't all go to hell like it would in a 2 faction game. The other two would still have enough soldiers to be able to fight the larger one. If one takes a lot of territory in Cyrodiil, that's just a lot of surface area contacting both of the other faction's territory, making the other two have to fight the more powerful one before they can fight eachother.
