I think the enemy MOB's attack range is shifted to the front of the main body. Slower enemy MOBs are less affected, but faster enemy MOBs have a much wider attack range and will be attacked before the player's attacks can reach them. The situation is even worse in multiplayer, where you can be attacked from 4-5 blocks away, and without a shield you can't do anything and get killed. There was no such problem until the previous version (1.15).
