"It helps that every example involves actually drawing the Lightning into the blade."
Provide quotes for this please.
"And inexperienced Padawans often being caught off-guard by Lightning."
Inexperienced padawans don't have as advanced precognition or augmentation as a Jedi Knight or someone with incredible raw power. Plus it's not a single bolt of energy but a sustained blast that they have to continuously block.
No it doesn't. They have nothing to compare to Kanan's feats in regards to Force power.
