Why does breaking dirt feel like breaking in survival? Why can't we spawn mobs? Why can't we use anything other than Redstone? Why can't we use tools and Armour? Why can't we be in creative and everyone else is in survivial? Why can't we place water and lava automatically? Why can't we explode tnt? Sure it's griefing,but if I see a private map where everyone can build,That's on the map creator because people will obviously grief. And if its a problem,just let map creators have the option to turn on/off tnt.
We have some plans to improve the experience in the creative mode, and plan to implement them in one of the future updates.
Good
