My few latest attempts with Greece made me think about Republic civic. While +1

per specialist is strong in right situation it takes a while to get going. Civic is also probably too strong after Industrial era for what is meant to be obsoleting civic.
So I thought how Republic could be made more useful in early game while weakening its late game potential. Solution I came up with: Keep the specialist slots and food penalties, but replace +1

/specialist with 1 free specialist per core city. (Isolationism's old effect)
That would make republic useful right away for classical era civilizations, while also avoiding late game supercities that get 15+ food from settled Great People.
