Actually really curious about that too. To my knowledge, current meta in 40k is classic "shit broke, everything is magic at this point." but with a large infusion of new tech courtesy of the Primaris releases. I would imagine that things probably haven't changed too much with tiny nuggets of higher end tech / archeotech sprinkled in that our suicidal Rogue Trader won't have access to. I can't imagine one of the primarch's being chill with sending rare gear on a suicide run.
