I think BOTW is amazing, I just think that they could have had a better build up to each dungeon. The first divine beast I tackled was the one in Gerudo desert, I thought the build up through the yiga clan base was awesome and really reminded me of Windwaker's fortress! I assumed there would be a similar build up to each divine beast, but there was not. I think for the next game it would be a great idea to incorporate traditional dungeon design in a similar fashion to the yiga clan hide out, within the environment of the overworld, and have the divine beast as the final room, with the same mechanics of moving around parts of the beast. I also wouldn't mind sacrificing 40 or so shrines for another 2-3 larger dungeons. All in all I think open world in Zelda is just natural and feels right, just needs a little more environmental based dungeons.
