We need an end update: here's why:
1.) The end is very boring compared to the nether, and the nether used to be just as boring before 1.16, so there needs to be some kind of balance.
2.) This would be a great opportunity to introduce new purple or black blocks, maybe even purple wood!
3.) The end could really just use more mobs in general, maybe something like a void strider, that hovers over the void?
