It's just the way he draws faces. It's among the least horrible of his faults.

"How many actual families do you see in Overwatch"
Well, since he's complaining about Emily (a character whos only appeared, in comics and such, not actually in-game yet) let's list a bunch of lore-important families from all multimedia pieces of OW.
-The Amari family: Ana and her unnamed Husband. parents of Fareeha/Pharah
-The Lindholm Family: Torbjorn, his wife, and several kids including Brigitte
-The Lacroix Family: Widowmaker/Emilia and her deceased husband Gerard
-The Shimada Crime Family: Hanzo and Genji are the children. Don't know much about the parents but they were probably cis straight Japanese Mafia members consisting of one man and one woman who gave birth to the duo.
-Orisa was created by Efi Oledele, a small African girl who lives with her parents in their city, Numbani.
That's off the top of my head.
