The changes made to the Savanna Plateau terrain post RTG 4.1.*.*, which is currently in use in 1.12 dev, has plateaus that are too high, too steep, and too closely resemble the Mesa Plateaus, which aren't very realistic for Savanna. They also lack proper checks for the surrounding area which can lead to strange artifacting from incomplete plateaus.

The old terrain was much better than this, so the terrain changes should be reverted.

Yeah its what i said a few times :P

Sometimes its even worse and you get like 8 huge plateaus that fills the whole biome haha

We should maybe reduce the height of, or remove, the second tier for 1.12 to make it look more natural.

Here's an example of the old Savannah Plateau terrain currently in 1.10:

can you like, having it have % of chance to get a 2nd layer ? that would be nice :)
