Make the Nether higher

The Nether update did a lot to make the nether an interesting dimension full of fantasy and danger. Unfortunately, only a year later, we would see the Cave update. Caves & Cliffs would do so much for the overworld, that the nether is kind of lame again. The nether in it's current form feels cramped and restricted. The terrain itself is great. The focus on verticality and weirdness makes it interesting to explore, but that soon ends when you hit the ceiling and floor. The nether's height is way too small, which goes against what makes the terrain so great. Doubling the height to 256 blocks will give the nether far more scope and scale, making it feel a lot more enchanting and interesting to explore. It would also give the player more space to build in, increasing intrinsic motivation.
