Manveer Heir is the game designer on ME:A and he is a well known and open racist posting pictures of himself drinking out of a cup with the writing "white tears" among other things.
The other guy seems to be getting all the blame for the ending in ME3
While browsing Manveer's twitter I came across this little gem he posted December 26, 2015:
I guess he used that as the inspiration for facial modeling in the game ending up with the toot toot faces.
But seriously with all the cries of racism and SJW bs that people have said has been plaguing the studio for some time now doesn't explain this shitstorm.
It's obvious the people that made ME:A just gave no fucks. They completely ignored established Lore, didn't bother writing a good story, terrible character designs including lackluster bad guys that even though are to be found in a different galaxy don't seem like fresh or different enemies than what we have seen previously.
All theses screenshots just prove how little anyone at EA/Bioware cared and none of them bothered to make an actual effort.
I was hoping for something great from ME:A.. but son I am disappoint.
