Why Taliyah and Sivr look nothing alike
I've seen a ton of people trying to justify their whining about Taliyah's appearance with "WELL, WHY DOESN'T SIVR HAVE HUGE EYEBROWS AND A BIGGER NOSE, TOO!?"
The answer is time. We have zero clue what the average Shuriman looks like, cause every Shuriman champ so far has been an ascended...or Rammus. Whatever he is.
Taliyah, to the best of our knowledge, is full blooded Shuriman. Parents, grandparents, etc are most likely pure Shuriman.
Sivr is a great, great, great etc descendant of Azir. Thousands of years of different genetics and people and what-have-you, until she came along. At best, she's maybe 1/16th Shuriman. I mean, Hell. I'm 1/16th Native American on my Grandpa's side, but I sure as Hell don't look like Geronimo.
In summation, Sivr is a diluted Shuriman, Taliyah is full-blooded. And that's why they don't look the same.
Least that's how I see it.
