I find that the new CS bonus is actually slowing my game pace. 1: The bonus for 1 envoy reduced from 2 to 1, for commercial CSs it reduces from 4 to 1. That's an early-game backslash, and will only turns positive when you have multiple T1 buildings running, which is dozens of turns later. 2: The T3 bonus is way too far-away. Even for holy sites it needs you to pick a belief and buy religious buildings, and one +3 T3 religious building is still of low-efficiency. Same for seaports, stock exchanges and broadcast towers, only research labs are going to benefit from this. And that's very late game. 3: Good things are that now you only need 1 envoy for T1 bonus and 3 for T2 bonus, but in general I think the overall bonus from CS is reduced not increased.
