To put forth an example, say that the Tatars had their team bonus as +2 LOS for Cav Archers in Castle Age, and then +3 LOS in Imperial. Or say that the Britons (who got their TB nerfed in the PUP) had their TB for 10% faster working Archery Ranges in Feudal, 15% in Castle, and 20% in Imperial. Or, as another example, say the Portuguese TB was changed to 15% faster research in Feudal, 20% in Castle, and 25% in Imperial Age. The list goes on.
I’ve always wondered why team bonuses never vary in effectiveness based on which age you’re in. This could be a neat way to help curb certain civs that might be too strong in team games, or to at least slow certain combos down in Feudal and early Castle Age.
The way I’d have it work is that the team bonuses would affect you based on which age you are in, not which age the provider of said team bonus is in. So, say you have a Briton ally who is in Castle Age, but you are in Imperial; you would get 20% faster-working AR’s while the Briton ally would only be getting 15%.
I wouldn’t do this for all team bonuses, but for certain civilizations it could be a good way to adjust them. But what do you think? Could this work, or is there some reason it wouldn’t?
