Weapon durability - awesome system, keeps you thinking about what weapons to use in what situations, encourages more tactical thinking. I've never once had a problem of running out of weapons in 120+ hours of playI say "really", because I for one consider the game to be blatantly overrated as is pretty much par for the course with Nintendos main franchises and because I secondly can list several complaints and areas that can be improved upon even in my favourite games, so I personally find it weird to hear someone say he can only list one thing he didn't like in a game.
Story - sure its minimal but I really like what's there
Side quests - there are some really fun ones, but mostly they are just filler to add more to do
Open world - best open world I've ever played in, its just so fun to meander around and explore. Shrines obviously give great rewards, and korok rewards are super useful
Combat - I like it a lot, its much more fun than most open world RPGs I've played (such as Skyrim, TW3), there's no skill points or anything like that but there's a good amount of depth to it.
Sure they could have added more or done some things differently but to me what is in the game is pretty much perfect and I wouldn't want to change any of it.
Also you say "really?" like its a surprising point of view when this is the best reviewed game in a long time and its very widely loved. I get that some people don't like it much but I just love it.
Weapon durability is bandaid solution Nintendo thought of because they couldn't design a combat system in which weapons are actually distinct and interesting enough to use, that people want to try the different type of weapons out themselves (like for instance something like Bloodborne or MHW manage), so instead they just made weapons break constantly. It never actually made me think about what weapons to use in which situation as, like you said yourself, you never are in danger of running out of weapons anyway. It simply made me avoid combat scenarios because they would just break my gear and because they mostly didn't provide worthwile rewards anyways.
I don't want filler side quests, that area is actually one of my biggest gripe with modern games, game worlds are getting bigger and bigger but the actual content filling these games is still often not up to snuff and BotW is a prime example of exactly that. Shrines are fine, even if their quality varies a lot, but I consider the side quests mostly garbage and Korok seeds not a good way to fill the map either, I remember collecting only about a hundred of those and not even handing all of them in and still never feeling any need to acquire more equipment slots.
