Yeah, Lucas’ spin on Vader even works for his weird midiclorian fixation. It’s like “Well he lost his arms and legs,so there’s not enough midiclorians running through his body now…so he’s less powerful”. Which isn’t great at all.
It actually doesn’t make sense because according to TPM sensitivity is determined by how much you have per cell. Every cell that remains is still just as connected to the force. By the logic to spite Vader, Yoda should be the least powerful Jedi on the Council.
