I think Alectai's getting at it that it doesn't feel very 40k for every guy in the army to effectively have the best armor. Even Custodes have varying shades of protection afaik.
Ah right that makes more sense then, but still, it would be a pretty understandable overreaction to a newfound fear of death in a people who were previously immortal / could reincarnate at will, so while it might not be true to the narrative of 40k (which loves beating up its factions for the sake of grimdark), we could be different.
Plus, the mental image of our guys making superheavy TEQ armour as a coping mechanism just feels weirdly on point with how different we are as a people from the other Craftworlders (They're over there lamenting about the loss of the Empire, we're over here cramming 1 inch thick wraithbone armour plating into every crevice we can fit on a power armour frame)
Edit: so the rat race begins.
