Strength or Weakness?

Something is wrong with these Architects... They seem to be weaker than the ones that besieged the Iron City. But how can that be, if the Architects absorb their experience and become stronger with every battle? They supposedly adapt to new weapons. So the young Architects should be stronger than the "older" ones from the first wave of invasion. But that's not what happened, so I want to understand why.
Could you please bring me some pieces of the destroyed Furies? I will study them.

Yes! This proves my theory. The bodies of Furies are not only stronger but older than those of other Architects.
You see, I have a hypothesis. It all is somehow connected with faith! When the Architects attacked the Hunters, nobody knew what they were and how could they be fought. And now when we are starting to press them back from the cities and have showed everyone that they are vulnerable, it seems as if it has debilitated them, or him - the Architect!
