I disagree. Voice acting for all the other characters is necessary. Don't voice link.
I can deal with items that don't necessarily have to be used outside of one dungeon to progress through the game, but the item needs to still remain useful for killig bad guys/ getting to new areas/ tackling a situation differently. Think if you have a dungeon you can either use the deku leaf to glide over a chasm or you can use the hookshot, whatever your preference is.
I will accept delays, especially if these delays are of the same type that allowed Zelda OOT to be so amazing.
