Okay this is kind of hard for me to describe but I will try and hope you understand. Before the patch, if I targeted someone and pressed a button that activates power word shield, it would put power word shield on them. They will get this debuff, weakened soul, that makes sure you can't power word shield them until the debuff runs out. If you would activate power word shield again, it would simply just not cast. Now after the patch when you power word shield someone who has the debuff after, the mouse icon thing starts to glow so you can click on another target. Is there any way to reverse this?
