overwatch-buns:

Looking at all the Omnics in the overwatch universe I noticed something I havent seen anybody else point out. The number of lights on an Omnics head vary somewhat for each Omnic as you can see:

These civilian Omnics from the tracer short only have three dots while Zenyatta and Mondatta have many more 

See?? I started to wonder if the number of lights maybe an indication of importance or what purpose they were made for and the new tracer comic and oasis map seems to Conflict with this as you can see with these two omnics with similar jobs but different number of lights. 

And then there’s bastion, who is an omnic with the job of being brute force only have one. 

I doubt the Omnics have a caste system but it might just be an indacator before the Omnic crisis on what job they have.
