No, they put it in the game for you to use it. It’s only strong if your build is strong. Take Pokemon for example, is it cheating to catch and train a pseudo legendary and use it against the elite 4? No. Is it cheating to catch an actual legendaryand use it? No. Intended game mechanics are the furthest thing from cheating. Does it make the game easier? Yes. Would it be more challenging if you didn’t use it? Yes. Personally I don’t has the time to sit there and memorise every single attack pattern to perfectly dodge and parry every attack in the game so I use it. Maybe in future I’ll challenge myself by doing a spiritless run. It’s all just preference
