[WH40K] Just binged on "if the emperor had text to speech" didn't get the joke with the ultramarines being able win most of the time. What's up with that?

Some years ago, a writer named Matt Ward was hired to write the codex for the Space Marines and some other stuff. A huge amount of stuff he made basically made the Ultramarines the center of the universe; that they had the best equipment, tactics, strategy, weapons, armor and so on, and that something close to 80% of all  the successor chapters were descended from the Ultramarines.

They basically became unstoppable Mary Sues, which is why there is a sort of anti-smurf sentiment that goes around the community as the Ultramarines basically steal the thunder from about every other major force in the Imperium except probably the Grey Knights.

Matt was a good writer for non-Imperium stuff, but his Space Marine work pretty much annoyed a lot of people.
