That's like saying that in an RPG, every battle that you do is "grinding" because you can run away from every battle. Yeah, most of the camps I come across, I go explore because a lot of them have some pretty good loot like elemental arrows. I end up killing some bokoblins as well. That still isn't "grinding". That is naturally playing the game. Grinding is going intentionally after Bokoblin camps all around the world because you don't have all of the materials.
No..... Shrines and Divine beasts make up the majority of the game. There's also hunting, cooking, gathering foods, sidequests, and treasure. That makes up 80% of the game. And like I said, you don't have to hardly any of the Korok seeds and the world still has plenty of things to do.
uhhhhh.... You can go hunting, try catching a horse, shield surfing, climbing mountains to glide easily to other places, exploring shrines, collecting insects, defeating enemies, talking to NPC's. I mean, the world is far more filled with stuff to do than Ocarina of Time, or Wind Waker, or Twilight Princess. So I must ask you... What was the point of exploring those worlds?
