Let me start by saying that I know they are different games but it's probably the only other game I can compare it with. I also know these games are not classic RPGs but when I see an inventory and stats on items in my mind those are at least RPG elements. I'm not a fan of RPGs but I have tried them before though I couldn't keep me interested enough to complete one :/
So I played HZD and I started enjoying it but after 25-30 hours I couldn't enjoy it anymore. Quest and side quests were kind of tedious for me, I know I was leveling up and getting a lot of useful items but I wasn't enjoying it anymore, even when I kept myself on the Main Quests I started to get tired of managing the inventory, go back to a merchant to get more shards, killing more machines, solving people's problems (for some reason I kept myself helping everybody, like I didn't have problems of my own), etc.
I have to admit that I enjoyed some fights, they were really fun and challenging but when I wanted to make progress it became annoying to not be able to move around the world without machines attacking me every mile, it felt like "random encounters" in games like Dragon Quest or Final Fantasy.
So, do you think it could be the same for me with BotW?
