The source for your figures literally says it DOES include expansions in literally the first line. Besides, even if I couldn't prove this (with the proof YOU provided), your asserstion would require that 5M people bought D1 or D2 and never made a character (30M RU for D1 and 15M RU for D2 adds up to 45M). That should be the first clue your numbers are BS. The second should be when you look for proof and it says unequivocally that you're wrong.
