I still don't see how you die in Zelda after LA. Not only is the combat easy but...
OoT: OP fairies that heal all your hearts. 3 of the bottles are easy to get and fairies are easier to obtain than potions. I never even need them because even when I make the stupidest of errors, the game gives me so many hearts that I'm seldom in any real danger of needing a fairy. But I'm not going to get into any elitist BS. The point still stands that will these easy-to-collect fairies, you're probably going to have between 40 and 60 hearts. How do you die with that?
MM: Even more easy-to-get bottles than OoT. But since you probably have less life, it averages back out at 40-60. How do you lose them all?
tWW: Same situation as OoT, but with OP soup in the mix as well.
TP: The fairies were nerfed and made a little harder to find, but even then, with so many hearts and so little damage, I can't see how you'd run out in the normal game.
SS: Fairies are still like TP and damage is increased, but the AI is easy to figure out and the shield is insanely OP.
But even in games where the enemies take a full heart, consider that you have around 10 hearts and healing items. In games like Mario 64, you have 8 lives and there are plenty of obstacles that take 3 damage and some take more. This almost never happens in Zelda. In SMG, you have 3 lives. And let's not forget all the things that can instantly kill you in Mario. This is very rare in Zelda. Most Zelda games don't even have instant-kill scenarios.
I can see someone creating a decent self challenge in Zelda, but for the normal game, Zelda is just so forgiving since OoT. Mario and Kirby will punish you for death with the smallest of errors while Zelda will allow the greatest of blunders. Again, with items, Link can easily obtain over 40 hearts in a world where enemies seldom do 1 damage.
Basically...imagine SMG where you have 40 lives, enemies still deal 1 damage, falling off the edge does 0-1 damage, there's almost nothing around to one hit kill you. The end result is Mario with Zelda mechanics and it'd be insanely easy.
