Slightly un-nerf the witch
So the witch has been nerfed several times and is no longer the OP threat she used to be. With low HP and low attack her biggest asset is her skeleton troops deployed. She also no longer lingers as far away from trouble and is more often in harms way. In order to make witches slightly more survivable in the chaos of war I recommend that, similar to the archer queens ability, that the witch becomes invisible for 0.1 seconds the moment she summons new troops. Why do this? Because it would re-establish her summoned troops as shields, forcing enemy defenses to untarget her and retarget on the skeletons. We all know that the moment a witch gets targeted she is dead. Let's change that.
