People seem to be under a weird misconception that primals are suddenly going to be absent from the story and/or are no longer a threat simply because means to counteract and cure tempering exist now.

At the core, they are still extremely powerful entities that were noted as taking entire regiments of trained soldiers to keep in check even in the case of the lunar primals that were undeniably weaker then their willfully-produced counterparts.

Foreign lands are not at the leisure of having access to those countermeasures, either, so I think it's a given we're still going to be running into them on the overseas continents and likely even in Ilsabard despite the strong Garlean presence.
