BoLS didn't really cover all the stratagems in their video, they focused more on the artifacts and warlord traits which they covered all of. They breezed over any of the stratagems mentioned in the previews, and just listed any stragems that were basically a copy past of codex: craftsworlds like fire&fade, the -1 to hit stratagem, screaming jets and of course wwp, and possibly another one I may have forgotten. They then mentioned a few of our specific ones like the mortal wounds cult stratagem for reavers/hellions, so definetly a couple they were missing. Way I see it though stratagems is something I'm content to wait on, it's mainly the pts costs I wanted to see so I could start list building.
