I agree more bosses and maybe a new outer realm like the nether. That and some kind of use for the lapis and emerald they are just useless at the moment and rare to find compared to stone and what not. surely the creators can come up with some use maybe an all in one tool can be crafted from them or something. To increase the difficulty make it where you have to have diamond tools to mine.
I would love to see some half blocks split top to bottom maybe even quartered for better detail and design features on builds. Also perhaps some corner blocks i don't know if that is possible this may have been mentioned before. (So pretty much a triangle)
To be honest I dont even remember. I have been playing mine craft for going on 2 years now and had no idea for the longest time this was even here. I think it was the minecraft.net but cant be for certain. In any advent it will be great to get to know some more minecrafters and see what all is out there. I have been out of the loop all this time.
