Is sage just scholar with a different skin?

Ruin II + Energy Drain, so you are still incorrect.

And who's "we". Some SCH players really seem to love using pluralis maiestatis.

We = the general posts and feature requests from the active posters in the healer forums over the past 3 or so years? At the very least the general sentiment.
And Ruin II + ED still isn't optimized, so no.

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.

Never said anything about spamming Eukrasian Diagnosis. Nor did I say anything about actually wasting a gcd for it (since that's what you seem to be insinuating).
And yes, you can literally spam ruin II non-stop. That doesn't mean you should do it.

Don't get me wrong. I'm not saying there's no value or that mobility isn't good on SCH in a variety of scenarios (prog?). I'm just saying it's another skill you want to avoid as much as possible when optimizing (so mobility gets pretty bad comparatively). Unlike SGE's options that already cover all movement requirements you can encounter.
