Zelda has had the same control scheme for the most part since the NES game - you pick a tool and you assign it to a button. It can't get any simpler without the game actually ripping the choice of buttons away from you.
There would be two people that would benefit from a random destruction of the control scheme like that. People who don't play video games, and people who suck at them. This thread was made by a person that sucks at them and as such it explain why the suggestions are just short of offensive.
The problem with TP wasn't that there were too many items. In fact, TP is a bit light on what Link can use and magic was removed entirely. No, the problem was that the items you got had limited use outside of the dungeons you obtained them in. I'll give Nintendo credit for introducing SEVERAL new items to the series in this game, though (as opposed to OoT which simply rehashed everything from LttP).
But what's even more hilarious than the godawful "simplification" of the control scheme is the actual opposite suggestions, like using C for the shield and controlled slashes. There would be no point in controlled slashes if the enemies don't have patterns, so it could easily turn into AoL with tough enemies that need to be hit in certain areas when confronted. Then we'll end up with another thread crying for more "simplifying."
