Is sage just scholar with a different skin?

Sorry, let me amend that comment with "in optimized play".

Ah yes, the "optimized play" of spamming Eukrasian Diagnosis to have access to Toxicron and having both of your movement options on 45 sec CD vs having a Ruin II on command without any requirements.
Unless you mean that you are talking optimized to the point of using in during downtime and calculating the exact three uses of toxicron, then yes.
