I think the problem here is that this is treated as a dichotomy. You're either Savage content or you're casual content, but it's like. Why call things "Hard mode" if it's going to be just another variation of the dungeon that isn't actually more difficult? And if Hard Mode is too difficult for you, then it's because it should be midcore difficulty, not proper casual.
To be clearer, I agree there's room for more difficulty in the game, but not necessarily harder casual content. We need more difficulty tiers in between.
