I didn't remove any from them. I think they should have some and I support your re-upping some of the culture on those. Agreed to a point. Particularly with % mods, the smaller the incremental increase due to tech improvements, the better, particularly the later the game gets. This is something I think we are all seeing emerge to be more true than ever with how extended our tech tree has become. The steps up in 'change' or flat +/- values, are good to continue a measured progression upwards through tech achievements and you've gotta have SOME increase in value for the% mods or they aren't an improvement over the previous versions BUT keeping those on a minimal increase path is a good option. That may allow the % mods to start a bit higher in the early game but get smaller gains than we've previously established through time. As a game theory, that should work.
