If You Were The Head Programmer Of Minecraft

In all seriousness-
More dungeons, temples and generated structures, e.g. fortresses, towers, farms
Much higher chances of mobs wielding weapons and wearing armor/special effect spiders
A new gamemode that's pretty much worldedit/voxelsniper
More special mobs
More magic!
More enchantments (poisonous sword, etc)
Fire arrows actually set fire to terrain
Special dungeon mobs wearing armor, similar to the More Dungeons mod
Better mod support
Creative flying looks better- More like Elytras
Capes are craftable and can be given banner patterns
Complex dungeons with difficult puzzles and OP loot
Better bosses! Some of the things people have done with commandblocks are amazing.
I'll add some more stuff later.

 

I would make a technology update, with different types of phones, tablets, computers, etc.

 

HAI
I HAS A SUGGESTION ITZ "how I will manage minecraft"
VISIBLE "LOLCraft"
BTW I will program the game so that just like ARK: Survival Evolved, the game does not trust clients with anything, essentially making the game near impossible to hack.
BTW I will also add more bow enchantments, for example enchantments that affect arrow speed (higher enchants make faster arrows), arrow trajectory arc (higher level makes arrows lighter and makes the bow more able to do sniping), and accuracy (higher level makes arrow firespread less).
HOW DUZ I PROGRAM
I HAS A I ITZ 0
