Definately more Blocks.!!!!!!!!!!!!!!
I'm a builder at Heart and i find that update content for use is extemely Lacking..
sure we get get a few new blocks and texture changesevery few updates. but we have to rely heavily on resource packs to get things looking right, how we want it and even then chances are it's been before.
before people say use Mods. for people who like to share worlds or Projects with others like me, it's a nightmare. mods and the game get updated and the worlds get corupted and un recoverable overtime. download links get broken etc.
Mojang needs to add a way for players to add custom blocks silimiar to Datapacks
