Raids are literally all this game has going for it. I guess dungeons too now, but those are just three player raids. All other content is just a pathetic joke once you luck your way to some arbitrary power level from grinding mindless strikes/the FotM activity or the pvp which is either absurd metagaming devoid of real skill or nonsensical chaos with no sense of competition. Raids are a halo product and practically the only thing a player might aspire to besides hopelessly grinding out a checklist. Diminishing them or, God forbid, removing them would be suicide unless the entire rest of the game was overhauled.
