Ok so the 2.0 version of this is now out. There is a few things that have immediately popped out to us.
Imperial Guard ability is awful compared to the others, needs rethought.
First Warrior ability is disgusting. Should very likely require a Fate Point expenditure.
Please make Trade Crafting. Its bugged me for 2 editions (BC and OW). Tech-Use does plenty, Trade is literally described as crafting stuff. Reassign this ability.
Untouchable, needs a complete rewrite, being an Untouchable means you can't be a Psyker. That is all. It gives you access to a bunch of talents but if you buy Untouchable at char creation it really doesn't do anything/ It is also terrible at being anti psyker. I would very much suggest rewriting it to just be an old style untouchable with a selection of abilities that you pick when you buy it.
This is just personal but just make Las Weapon Variable setting a special rule, there is no reason for it not to be.
I'm sure there is more but this is what immediately came to our attention.
