For a game with Minecraft in the title, there's literally no mining or crafting. There's no classes. Any attempts to build your own class is thwarted when you get new gear that rewards you to throw away the symbiance you were trying to make to do more dps just smashing your fancy new hammer. As you progress your numbers go up so fast that your playstyle is determined by what gear drops instead of grinding for the gear you want like any other dungeon crawler. If you play with someone different, you just have to all start new characters or the highest level person will just roll through while everyone else dies. There is no plot.
