I disagree HEAVILY with the bolded. Instead of removing those elements entirely there should be ways to manage them. There should be a way to preform maintenance on weapons when near a fireplace, the climbing problems during rain and slow climbing can be both solved with an optional upgrade (let's call them "claws") that has to be earned.
Combat wise the only things I'd want is to be able to defend with a broadsword: They can let you take chip damage so Shields will still have a use and let you parry without having to put up your broadsword to then grab your shield, and to have link preform his best Captain America impression - to have the ability to throw shields.
Yeah that suggestion is disgusting. At least, he suggests that they also change every other aspect of the game. The appeal of Breath of the Wild, exploring places and finding treasure, cool elemental weapons that function as tools, the ability to get any weapon that an enemy is using, shrine rewards being useful, are all enabled by the fact that weapons break. They could balance the system a lot better, but I think it deserves another attempt.
Also I can appreciate the hold and cook mechanics because it shows their commitment to letting their gameplay systems dictate all interactions through the same interface. They don't want a wildly varied "cooking" interface. The way you toss elemental chuchu jellys, drop items, drop food, toss bait, cook, create balloons, create fire, are all done using the same interface. It can be clunky and confusing, but its important for encouraging experimentation.
