I wanted one good scene between Duryodhan and Karna before the death of the latter. He had interactions with Gandhari, Kunti everyone before death but at least one scene with Duryodhan was so needed here. Irrespective of his conduct and everything, Duryodhan was the most important person in his life and the last interaction that they had was harsh fights with Duryodhan doesn't understanding his feelings. There should have been one sweet scene where they just spent time with each others with confidence
As it is all the after death scenes of his are with the Pandavas imagining him
