Re: coarse dirt: if it's a replacement for "grassless" dirt then why bother adding in a new block? Isn't it just a texture change at this point?
The coarse dirt actually exists in 1.7 in savannahs but can not be obtained (even with Silk Touch), while in 1.8 it will be both obtainable and craftable with normal dirt and gravel. So you could say "coarse dirt" was already a thing, MogMiner just gave it a texture and some mechanic changes.
I personally think this is Mojang taking a step in the right direction FOR ONCE. I mean, Oceans just got some attention, and Sponges now have a use. This proves Mojang DOES have at least one employee with a brain.
I saw a few other people say this, but holy fps...My pc isn't a beast but it certaintly is plenty for Minecraft; I usually get over 100 fps on far 16 render distance, but with this snapshot i had to turn it down to 3 for it to even be playable at ~25 fps.
