Maybe there will be a new SE where Vader storms the Blockade Runner instead of sending in his troops first. You know, to match that stupid Rogue One
endingmovie.
We didn’t see Vader board the ship in R1. The troops could have come in first. It was a much larger ship, and badly damaged. The troops had probably fanned out searching everywhere, and Vader found the fleeing rebels first.
The Blockade Runner was captured, mostly intact, and resistance was to be expected.
For further critiques of R1, take it the the appropriate thread.
