I can't think of a single game that manages to have enemies correspond to your level rather than area or story progression actually contribute to the game. It just makes trying to get better gear ultimately a pointless task because the enemies get strong at the same rate so you might as well stay weak.
Guild Wars 2 did a relatively decent job where you'd scale to the area, but having good gear did make a notable difference so you didn't stomp around new areas like a god, but you were also still noticing an improvement.
