Anyone else think jeb is going a little to far?

Armored Mobs and Ability totems? Minecraft is becoming a little more complicated than it needs to be. In my opinion Minecraft only needs two more things... more mobs and more potions. once this is achieved the game will be well balanced, jeb is focusing too much on single player and not enough on the Multiplayer game Minecraft has become. Just my thoughts. What do you guys think?
