Because all they know how to do is copy and paste, They had the answer right in front of them with the Legendary WQ Campaign, which was at a good difficulty level without any champions or modifiers. Just more beefy enemies and a new threat being the Hive Guardian using a super against you. For some reason they have made all content feel the same. Master raids, master dungeons, Grandmaster nightfall, etc, all feel the same. Match game, champions, etc. They just copy and paste this to everything and it becomes so boring. They need to make content challenging without champions and modifiers. They can do it. We see that clearly with the legendary campaign. They need to add contest to raids with extra loot incentive, and add some sort of hard mode dungeons without champions and modifiers. Just beefy enemies with limited revives like hard mode raids in D1.
