The idea is about as simple as it gets: wool should reduce falling damage. I'd say the reduction should be about 30-40% of the cushion caused by water. Leaves should also act as a cushion (10-20%) and--if they ever make an appearance again--sponges (40-50%)

I think soul sand should do 5-15% fall damage reduction. And factor in the soul sand block height of 15/16 of a block in it.
Yes, but water isn't all the aesthetic. I was thinking about this when I was building my house and I kept falling three meters onto my wool floor and taking half a heart of damage.

Why does everyone think I don't have an avatar? Is there anyone who can see the one black pixel.
