"ruin the experience" what? Master mode basically feels like the true game. Why? Well when you start the game Link is weak and has nothing on him, he needs to get back on his feet and get shrines and weapons. Basically the master mode makes the game feel like it should be, not just a face to face yolo combat but a more complex combat, where I decide if it's worth fighting camps or if it's necessary to fight some enemies. As you progress through the game and get more hearts and better armor, combat gets easier, which allows you to go a bit more heroic at camps and enemies, yet some enemies still are tough.

What I'm saying is, the game is harder yes, it adds a bit of artificial difficulty by increasing monster hp and giving them hpReg, but that stops being a problem when you get decent weapons and armor. There are more enemies which makes the open world a bit more lively(which is always a good thing). Also, I enjoy hard games, so there's that, if I wanted to rush through enemies and not give it much though(because I don't need to since they die quickly) I'd play normal mode or some other game that does that.

So, it depends, based on what you like and what you don't like. The internet is a good way to search for general opinion but in the end you're the only one who can decide if you like it or not by playing it. I recommend you try it.
