I'm not going to complain how OP Fiora is
Yeah she is a though one to deal with but there are worse. But why does she have AOE heal? Now I get why she could heal HERSELF, like "I killed you with 100 hp left and now your buddy/tower can't punish me for that, sucks to be you", that makes sense with her kit and theme, but why would she heal her teammates, potentially more than Wish or Monsoon would?
