Currently, when you give a tome with cooldown to ally, the ally would have two different cooldown based on which slot the tome is put.

If the tome is put on inventory slot, its cooldown refreshes.
If the tome is put on backpack slot, it keeps its cooldown like other shareable items.

It confuses some people.

Remove the cooldown of the tome on backpack slot and stash slot, just like how it is on inventory slot.
