AHC: Black Death affects a different area (or areas) of the world

Have the Black Death affect other parts of the world as severe as it did in Europe, BUT, Europe remains relatively unaffected, with deaths being only as high as 5%.

If the first paragraph made little sense, then what I meant was that have the Black Death affect China, India, and the Muslim World much more worst than it did in OTL Europe. What could the effects be?

RULES:
1. The Black Death can only reach as far into Europe as Poland and Bulgaria
2. In the Middle East, the Black Death must have a 10% death rate at the minimum. Go crazy at the maximum
3. 15% death rates for China and India. Again, go crazy at the maximum
4. If plausible, Europe SHOULD colonize as OTL

Bonus Points:
1. If colonization occurs, larger European settlements in China. (Definitely larger than those concessions, Hong Kong, and Macau)
2. Deeper penetration (hehe) of the Black Death into Africa
3. A larger Byzantine Empire
4. Complete Chinese Balkanization
5. A surviving Mongol Empire
 
Before the Black Death devastated Europe, many cities in the Islamic World and entire Chinese provinces saw death rates which easily exceeded European ones. So this is OTL.
