Revert the changes to attribute swapping

Removing attribute swapping is a monumental mistake on Mojang's end and unnecessarily alienates millions upon millions of players. Attribute swapping has become a firmly engrained aspect of Minecraft PVP and its removal would cause a significant amount of this game's skill expression to simply disappear. This change would affect mace and spear like others have mentioned but also any game mode that includes a shield, that being nearly all of them. A change this large could cause a rift in versions akin to the 1.8 to 1.9 split. I see no reason that attribute swapping should be removed as other bugs that have been engrained into Minecraft to the same extent remain. The two best examples of this I can think of off the top of my head are quasi connectivity and tnt dupers. I urge Mojang to realize the gravity of this decision and revert these changes.
