ALBW is a really easy game as far as death failure, you'd have to really try hard to die in it. It's one of the big problems with it. So you want to try silly stuff out...why don't you just save beforehand? If it's on the overworld, you have plenty of places to save. If it's in a dungeon, well you've already said you think the dungeons are short and easy, so what's your issue again? You make it sound like warping between Link's house and a dungeon is really hard. Youre not making any sense.
I didn't find your initial argument flawed, I just disagree that the dungeons are easier than the shrines and the divine beasts. Most of the shrines and the divine beasts are pretty easy, hell the name of the challenges in shrines telegraph everything. Dungeons have the same rotate the thing to shift a room around, some like Rudania are incredibly simple.
Complaining about having to grind for rupees to buy equipement in a game where you don't need to grind while also lambasting the game for giving you rupees as rewards everywhere is pretty contradictory. You keep making nonsensical complaints for I'm not sure what reason.
