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.
It's lazy from a design perspective, the coding is just as hard and crunched either way. Not to be a treat defender, but I'd prefer we get no games, shorter games, or less coherently playable games(either due to bizarre mechanics or frequent bugs) than less fun games.
