I am actually talking about the known details about the Ancients. It is true that Ancients have been noted to create many techniques but the known Ancients have seldom demonstrated those techniques through the Force themselves.
And Ragnos is the only true saving face for the Ancients. But even he did not initiated any expansionist moves like Naga Sadow did, because he knew about the immense risks of such an action. Thus his skills have remain untested.
Additionally, Malachor V is the place from where Kriea, Revan, Sion and Nihilus learned much about the ancient Sith techniques. And possibly the "True Sith" had inhabited it before Revan discovered that planet. And the identity of the True Sith has not been revealed yet.
And not all tools used by KOTOR era Sith were actually developed by the Ancient Sith. Best example is the Star Forge.
