Misanthrope Prime
Hero
There's a reason we call BECMI "BECMI". It incorporated the power curve into gameplay and mechanics to a degree that "advanced" D&D has failed to do. The "I" in BECMI tells you how to become a god, basically, and incorporated that into the world and gameplay of Mystara. Contemporary "advanced" D&D just tells 20th level wizards "IDK take another epic feat lmao".To me, that's an issue with D&D's power curve, not Eberron as a setting. I can't think of any setting's internal consistency that survives the core premise. Ravenloft is less scary when your more powerful than the Dark Lords, Dragonlance stops feeling epic when you can solo most dragons and Dark Sun stops feeling like a survival sim when you can start slapping around Sorcerer Kings. Just the nature of the beast imho.
