My opinion about some controversial civ designs in AoE3

To start with, I have been playing AoE3 multiplayer for 3 past weeks (been playing AoE3 single player since childhood and AoE2 DE multiplayer for 4 years)

​

• "The available one age earlier" should just go away. The fact that it just makes some of new AoE2 civs cringe is that devs adding these things. Now in AoE3, the things like Portuguese getting TC one age earlier, some civs getting skirms one age earlier, US getting Factory one age earlier. These things make the game fairly imbalanced but fun in single player perspective.
• Free resource buildings makes it imbalanced. In AoE2, Feitoria was a building that takes up 20 pop and generates resources but this building is frowned upon as it becomes unfair. In AoE3, dutch banks, japanese shrines, swede torps, inca houses all belong to this category. I won't say factory as it is available to all European civs.
• Also, I very well know that some civs lose something in return for their strong bonus but the point is buildings can't be destroyed so easily as villagers which makes the raiding hard and available one age earlier doesn't make it look so good. Imagine a civ getting cannons in Commerce Age. We imagined it before, but they are available in Sweden which is just not so good for design of the game.
