In 1986, which BotW is touted to be similar to, half the reason for fighting enemies on the overworld is because they'd rape your ass otherwise.
It was essentially a lite version of bullet hell, especially as the game progressed, nevermind the Dark Nuts inside of late dungeons, crikey.
BotW isn't so much Action-Adventure as it is Garry's Mod. Hey look, you can do these things if you want, I don't care. That's the BotW design approach, and the design work that went into the individual elements reflect that lackluster attitude.
BotW has nowhere near the best or even decent combat.
The puzzles are piss easy, sometimes not even bordering on puzzles so much as just padding.
What else is there even? I guess you could explore the weak architecture in the world design, if you like the absence of lore and finding 900-odd fava beans.
tl;dr They wanted to be the best in faffing about in a forgettable landscape, and they abso-fucking-lutely hit the nail on the head.
Back to playing actual video games.
