unfortunately i think there were better solutions to the former (extrapolate advantages to the other eras, or give a broad universal ability in addition to the traditional era-based ones)I get why they did this. The stated reason that they want civ bonuses to always feel powerful, so linking civs to specific ages makes sense. The unstated reason, IMO, is that this makes it even easier for them to sell DLCs. It's far easier to design a civ for a specific age than it is to make a civ that's appealing throughout the whole game.
the latter is what it is, but i’m not too happy about the outcome
