I absolutely love the look of the new caves with the last snapshot and I really can't wait to get in there and start building some nice cave dwellings and dwarf halls. I scrolled through the whole thread and a couple predictions have come true: Stronghold generation from what I've seen is pretty messed up. There's definitely gonna have to be an overhaul to get that all sorted out. I really wonder if they aren't gonna revamp and move strongholds to the deep dark and let the wardens be the single guardian of the portal. I know Mojang said they weren't end-related, but that kinda counts, right? Also actually loving the way mineshafts look now. So many of them have bridges that just pass from one wall of the cave, over a giant chasm, and then right back. It's gonna be so much fun exploring those now.
As for my other thoughts: I'm glad the glowsquid won, it was one I originally voted for. I figured it was gonna drop some kind of glowing ink. It's a squid after all so that was pretty much a given. I really didn't want another hostile, I feel like the game is just littered with those at this point. And the moobloom sounded pretty boring. I just hope that the glow sac gets fully implemented as a dye in the future, making it possible to use with anything that can be dyed like armor, sheep, wool, and maybe glass and concrete and all that. Having a structure that you can see in the dark would be so cool.
And finally, I'm with a lot of people when it comes to archeology. I don't mind it overall but don't really feel like the purpose of making clay pots is worth it. The brush texture will also really need to be changed. If it looked a little more basic I might be a little more inclined to it
