Lol you actually point out that war is a great time to see rapid growth but failed to connect the dots with the Brotherhood.

I'm not saying they totally stagnated and got nowhere. I'm sure every Sith who fought in the war grew to an extent from it. That doesn't preclude the possibility that these Sith are weaker than Sith from other eras.
