The spawn rate for zombie pigman, wither skeletons, blazes, ghasts, and magma cubs have lowered and they don't spawn as much as minecraft pc or minecraft console editions.
MCPE-19350
Not a lot of mobs spawn in the nether any more.

I am on Win 10, I have to stand in the open for around 10 mins before a ghast appears. I don't mind not getting swarmed by them like before but its hard to get ghast tears when they RARELY spawn.
