Artembankin,
Your scope is too narrow. You are not the only Kemper user and the Kemper is not only for people that do mixing/mastering. Profiles are not just for the goal you described.
When evaluating a profile, some of us would also like to hear what "non-professional" or "amateur" users can create. If they can create something with potential, using their limited resources, then I can extrapolate that to fit my skills and expectations. Not all of us base our buying decisions on one single perfectly mixed demo. If you cannot evaluate the quality of a tone from his demo, and require a perfect mix to ascertain usefulness, then perhaps your skills need some improvement.
My point in addressing you was that, your songs and mixing abilities are not perfect. They are above average. So to beat your chest and degrade someone else's contribution only accomplishes two things: it discourages other "amateur" users from making demos, and, it makes you look like a big douche.
Neither of those outcomes are good, so maybe your negative thoughts and opinions are better kept to yourself. Not all of us are only interested in perfectly mixed demos and appreciate what more common users are able to contribute.
