I think Bite has the right sentiment, but maybe not the right details. I do not think culture or science should be a base yield. Having culture as a base yield caused some big problems IIRC, there is a reason all culture has been moved behind monopolies or improvements. I would try faith on a base yield on exactly incense (but only incense). are the premium yields, you should only get one of those from a lux, not two different kinds, UNLESS the luxury is flawed in some other way. For example the current incense is fine (actually a bit weak) even though it has faith and culture, because it's base sucks. Incense is well designed IMO, big upside but big downside. Changes how you approach things. I think faith and culture ought to be a bit more rare too. It should be a nice treat when you get access to a rare yield, I feel like I get a faith monopoly every 4th game (and coral is almost a faith luxury too). All 3 faith plantations lead to very similar early game.
