Regarding the Progress changes: switching the 2
/2
to Expertise seems like a straight up buff (at least for my play style). While the early worker from Liberty is nice the main reason I take that policy is to get to the policy hidden behind it. Now most games I'll build/buy my initial worker and go down the left side of the tree, getting that sweet 10 culture per building while my cities are building Shrines and Monuments.
Fraternity, as good as it is, is normally the next to last policy I unlock anyway and this rearrangement won't change that. The free worker and civilian benefits will be unlocked later but I'll still get a ton of use out of it.
I'll miss the 5% reduction in policy costs but that was likely too much scaling long term benefit combined with the reduction in building costs for one early tree. The reduced happiness threshold is a nice consolation for losing that perk.
