I agree and disagree with what you said about obi wan.

Was it the best Vader ever? Yes.

Did obi wan give it? No. No sadly. They stole it from the Force Unleashed and Jedi Survivor games like shot for shot beat for beat and they watered the moments down to make them work.

One of those games is no longer canon under this version of Star Wars... So like... Just steal the entire plot please it was giving amazing. Just make that one whole season.
