Minecraft wiki entry for Development_versions, associated text: Reason given by Jeb: "Feedback from PvP players was that it added a tactical layer and options when fighting. Since the charged attacks were reintroduced, I had to redesign how the "quick misses" work. A miss will not count as a charged attack - you need to wait for the full duration of the weapon's original delay. Because of code organization, the penalty for auto-attacking is now specifically 1 tick, instead of 20% of the current weapon's delay. Note: Base reach is still 3, it has not been reverted to 2.5 as in v5."
