This question already has an answer here:
Having watched A New Hope again, I have just realised that the only people to meet Vader in person out of the main good characters are Leia and Obi-Wan. It's understandable why Han didn't interact with Vader but why doesn't our main hero do so like in all other movies?
Not a dupe of this question. I don't believe the answers in there actually answer my question.
I know there were plans for Luke to be told that Vader was his father but I find it odd that there was no pre-reveal meeting between the two of them such that both of them would have an initial impression as to who they were dealing with (that IMO would have made the reveal even deeper to Luke than what is actually portrayed). After all, Luke was told about Vader's reputation by Obi-Wan and Vader had sensed that Luke was somehow connected to the force.
