I'd say because, for the most part, as far as the show was concerned, if it wasn't happening in Camelot, it wasn't happening.

Logically, the Sarrum should have been targeted by sorcerers but, at the same time, it would also have been logical for a ruler who fancied more territory to take advantage of the anti-magic laws in Camelot, and possibly other kingdoms, to recruit sorcerers from Camelot, who have every reason to hate Uther, to help bring him down. We know that King Alined was cool with using magic to serve his purposes. Recruit enough angry, dispossessed magic users, many of whom will have lost loved ones to the Great Purge, and they could do a lot of damage.
