Witches can summon Wither Skeletons!

A Witch is a mob in Minecraft that is able to throw Splash Potions and drink Healing Potions. But one more ability should be added for the Witch. When she sees a Villager, a player or while in a Raid, she should be able to summon 2 Wither Skeletons. She can do this only once 2 minutes. Both the Wither Skeletons should give their first priority to attack the mob first targeted by the Witch, and then go to their original behaviour. This should add some more fun in the combat. I hope Minecraft adds this in their next update.
