What's untouchable, what's not?

[DustyPorViva]

I'm interested in hearing at what you guys think are 'untouchable' aspects of the 'classic' experience. From storyline, to game mechanics, to even the simplest things. Also, what do you think would benefit from being changed?

Some examples:
> Do you think it'd be okay to change the + explosions with something more natural looking?
> Would it be okay if players moved slightly slower while carrying an object?
> What if players no longer blocked?
> Which do you think is more appropriate? Birdshot or Hookshot?
> What if the 'default' speed was increased?
> What if swords got an upgrade? AKA, higher levels swords being able to slash right through signs/stones/pots?

Simply, if you've ever thought, "please, don't change that!" or, "oh man, why did they change that, it sucks now?!?" or, "I wish this would be changed to do this/that". I wanna hear it. Like I said, could be gameplay mechanics, could be storyline, could be graphic related. I think it'd be healthy to know what players think about this sort of stuff, since I believe these sort of aspects are very important to what Classic is.
