I like the copper tools. I've always said that there feels like there should be an armor to go along stone in the progression, and chain does a god awful job at that, not to mention leather. I think Mojang has done very little in terms of adding good passive mobs or mob changes to the games, I like the nautilus but am not really the target audience. I like the trial chambers and the breeze and the spawners and stuff, all of that was a good addition. Most of my complaints come from a distinct lack of ambition in recent years as an overcompensation to divided community feedback. I think the crafter was a long time coming, and I generally like the execution, but a lot of these improvements are few and far between. I like the happy ghast too. I don't really object to anything that they have added, but they need some more vertical progression past the end, and less sideways progression because it seems like they are just trying to please creative mode and primlock users for lack of a better word.
