I don't like it, the conception of shields, energy, completely overhauled the PvPing. Used to be one click = damage health, and that is what most people liked (including me). I don't play minecraft anymore partly because of the update, and how FUCKIN TOXIC!!!!! the community is now.
Enchanted golden apples (gapples, notch apples, whatever you call them) are no longer craftable as of the Combat Update. However, they can be found in loot chests (chests in desert temples, dungeons, End Cities, etc.), which is determined by the new loot table attribute.
