To be fair, while SWAT was that way, R6 is based on a book that is all story.
My bigger beef is that the game isn't setup for single play. Whether there is some thread connecting it or not, I want to be able to play it alone but NOT by myself. Previous R6 games gave you a team of AI. Sure, they could be a pain and get in the way, but once you learned their limits you could plan and place them where they would be the most help.
Now there is no planning, no intel beyond what you collect with drones yourself, and no friendly AI.
