The Lantern! Because I thought it was underused in TP. They could have made us use it in so many other spots! like make some of the dungeon rooms dark, and more caves around Hyrule would have been nice, there were too few in my opinion. I'd like to see them expand on the lantern item in 3D games. I think it could become a very useful item if they found a few more applications for it and forced us too depend on it more often. The wolf sense eventually made the lantern a waste of fuel so this time in SS I hope they put some more thought into a lantern item.
