I've noticed that since the 1.16 Nether update to bedrock, the Ghast spawn rate has increased tremendously. Before, there might have been three Ghasts in half an hour if you were lucky, now they spawn every 30-45 seconds within at least fifteen blocks of my player entity. I couldn't type five characters into a sign before another one spawned and blew up the sign. Last I explored the new biomes, in half an hour I had obtained 15 Ghast tears, not counting the at least ten that fell into lava. The spawn rate isn't specifically high to any biome, they all (except the Warped Forest and Basalt Delta) Spawn the same high amount. This is NORMAL difficulty, not hard. Please if possible maybe lower the spawn rate slightly, or at least don't have them spawn in your face.
