They're just tripping balls on adding more and more power to redstone and devices with zero regard for any kind of underlying design, internal consistency, or anything at all really.
The hopper is what bugs me, how does it pull out of inventories and pipe things sideways? Classic example of Mojang taking a cool mod idea, and killing it.
This one is my personal favourite, nice to know you went to all the effort of making a trapped chest- then undermine it with this functionality in the same update.
Nether quartz, its not as though we had several other near useless ores in vMC that could fulfil the redstone mechanics, why do we need another? Nether gameplay?- this is just another smash and grab resource that adds little reason to STAY in the nether.
(There was one reason to stay, but they killed that by making netherwart grow in the overworld)
Essentially it's turned the nether into just another mining trip for the sake of something pretty.
Don't you just love how Mojang now treats everyone's worlds as disposable?
and still no mod API, the one thing Dinnerbone was hired to do and we still don't have it. Their not even giving an ETA for it anymore. (so its probably not going to happen).
