Sorry, I think you lost me. You decreased 'appearance', to raise your 'aim', which appeared to be successful. But how does that demonstrate the importance of 'appearance'. I would think it demonstrates the importance of 'aim' more so. In any case, I think you're right that you need some of both. If for no other reason than to protect your own attack value. Of course, with no 'aim', you have no attack value to begin with.
