You could argue that by their very nature, all Primarchs were psykers of some sorts, basically being Greater Demons incarnated into flesh bodies.
Yeah agreed.
Replace 'psyker' with 'creature of the warp' and it's perfect.
All of them are created using powers from the warp, so it's not incoceivable at all that even those that display no
raw psychic talent may manifest in different ways.
Besides, there's no actual evidence that in order to be a Perpetual you have to also display other psychic powers.
