I'm not sure why everyone is hating on the OP. Level design is crucial when building an expereince for a player. I've never played DS, but just limiting the player's movement with cliffs in a battle with an enemy is enough to make the game feel harder.
All that aside, I think the OP makes at least one solid point: why redesign a game around people who don't want to play it? All that will do is piss off the people that liked your game in the first place, because of the way it was designed. Let those people go play another game, and leave this one to the fans that want it to be the way it is. I've lost a good few favorite franchises because of moves like this. Soon, there won't be anything left that is fun to play.
