Well we actually don't know how often they appear. Deaton said something about them appearing every 100 years, BUT, to me (this is my interpretation) it sounded like this was supposed to mean it's pretty rare... Plus most of the time, when an alpha dies another rises. So the death of an alpha rarely means that the total number of alpha's is reduced.
