I'm not an expert in this (read: I cannot yet reach your level of dps
) but the folks at mmo-mechanics spent some time working out sage/sorcerer dps rotations:
Hybrid is discussed about halfway down the page. Their suggested rotation mentions that Shock (Project) is inefficient DpE wise but is useful when you need to be mobile. Also their hybrid build includes two points in Chain Shock (Upheaval) which would increase the average dps of Project over time.
