As I said we will still dont have all the info... and again as I said, if Aetherflow still works as it does currently and is still available to SCH, then SCH will not need to take Lucid Dream as a shared role action.
EDIT: I also need to make a potential retraction. It is very possible I have made an error. I assumed that the Drain skill on the caster dps shared role actions was a replacement for the ACN/SMN/SCH Energy Drain skill. This is very likely not the case which means SCH almost certainly won't need Lucid Dream. So consider my foot in mouth regarding SCH. I'm not too proud to admit when I'm very likely wrong.
