Ghast Spawn Rate out of control

Whenever I am in the Nether, I notice that Ghasts spawn like crazy, and one or two will immediately spawn, even though I am in the Nether Wastelands biome, which shouldnt have that high of a spawn rate such as one that would be present in the Soulsand Valley. As soon as i go through the portal, one or two ghasts will very shortly after spawn, and after i kill all ghasts present, a 30 seconds do not pass until one or two more have spawned yet again! I understand ghasts can still spawn in the Wastelands biome, but they are spawning as if i was in a soulsand valley, and it makes it really aggravating and irritating having to bow down ghasts who are constantly shooting at you every 20 seconds, in which i go through a stack of arrows every time i go to the nether. Please fix the spawn rate of ghasts, for they are making the Nether even more of a hell than it already is (no pun intended).
