I think BoTW is potentially the most overrated game of all time. I liked it. But would replay it now that I know all the puzzle solutions? Probably not. Dark souls is more replayable in my opinion due to the multiple builds etc.
I do from reading the web. I also managed to find that boss when exploring after the invasion. But I did not bother to fight it. Boss mechanics seem rather out of place for the game. Is there a way to safe him from becoming?
