the darknuts in twilight princess compared to the darknuts in wind waker was a step in the right direction,they should build more on that for the rest of the enemies
Very first thing that comes to mind: The fact that you don't really use items outside of that specific dungeon. Wind Waker did soooo much better with that, but for the most part in the games, you get the item, use it in that dungeon, and you use it maybe once, twice tops, again.
