Why do I complain about DBs?

Someone actually needs proof that DB's clearly have a completely biased potential compared to any other classes? It couldn't be deduced with common sense?

This is the very problem they had with CautionSin. What he perceived to be "common sense" was unable to be backed up with proof. Though you're on the opposite end of the spectrum of CautionSin in terms of where he stands, the very nature of what you're trying to do is the same as his: trying to make generalizations without any solid evidence. Numbers matter more in this topic than anything else, be the fact your assumptions are right or wrong. The majority residents of Southperry aren't foolish enough to maintain their arguments when solid proven facts lie before their eyes.
