Emperor
Freedom also has Arsenal of Democracy. A straight boost towards unit production is going to help a domination victory. So that's two tenants that are directly tied to domination.
Freedom doesn't have any happiness boosts tied directly to conquest like Autocracy and Order do but it's certainly much better for domination than the other two are for the victory conditions they aren't supposed to aim for. It's not super imbalanced or anything but it is a slap in the face to the professed game design so it's one of those things that really bugs me. >.>
I agree the other two are shorted a bit... but come on, the happiness is huge! Freedom's policies already don't scale to small cities - there is no cheap happiness for Freedom once you add cities that aren't already fully constructed and staffed with specialists. That's why foreign legion makes sense for smacking someone down but not conquering them. As Venice I ran over the Huns with my fl's but razed every city I took, going one at a time to avoid upping my science costs.
If you conquered with freedom you would be throwing away the whole tree.
