Maybe I could help you to notice that Warshades are Science origin, not Natural 
There are very good story reasons why Peacebringers are all natural (those powers are common to every single member of the Kheldian race who hasn't undergone the Nictus process) and why all 4 VEATs are natural (they all begin as un-augmented humans given training/equipment - Fortunatas/Widows don't get psi-powers until they branch, and Banes/Crabs don't get their arguably sci/tech powers until they branch, but at the beginning of the character they are all natural humans).
then I didnt notice that
But as soon as you hit level 10 you do whatever you like with your character, you dont need to be human anymore, in fact, you dont have to be human at all as there are some non-human face options and different coulourable skins

Sorry to give a callous reply, but a big part of EATs is that they have established plotlines and origins. Yes you can look non-human from level 10 on a VEAT, but you'll still look like an average Joe when you go into costume 1.
Edited for atrocious spelling, will see Miss after class.
You're not meant to have as much freedom in deciding an EAT's background. It's already in the in-game storyline.

Yeah you can do that, but if you care about the lore you probably wouldn't And if you don't care about the lore then why would you even care what your origin is?
I cant help noticing that VEATS and HEATS have to stick to a natural origin, but that seems unfair to players who want thier character to be of a different origin, I have a few short descriptions of an origin based VEAT/HEAT
VEATS
magic - a fortunata gained mystical psichic powers manifested within her mind making psichics easy
technology - a Robotic crab spider unit built to eliminate targets with its assault mechanisms
science - a Bane spider super serum project was succesful creating a superhuman arachnos
Mutation - a normal person who grew stingers when stricken with a mutant virus making a perfect widow
HEATS
magic - using a binding spell to merge with a kheldian entity created a mystical entity of energy
technolgy - a robot that can shapeshift by using DNA from a kheldian entity
science - an experiment to infuse kheldian energy into a human to create a Kheldian/human hybrid
mutation - strands of cosmic energy transformed someone into a kheldian entity when traveling in space
