Voiding anvils is probably a good thing. It made it less about the characters and more about people who could make the characters. EDIT: Apparently I did that.
"Lightningbound" golems were just the early concept for golems without souls. That concept was implemented as Thanhic Golems in Anthos. Sounds like you mean something else though.
Multi-core just doesn't make sense. That'd be like a car with four steering wheels.
