With the new mercy...

I think it might be time too reïntroduce an old reaper concept. An old concept with the reaper souls he used to get after a kill was that after he picked up their souls mercy would no longer be able to res that character. With res beeing so strong now and mercy practically beeing a "must pick" with a +90% pickrate across all ranks. It would be cool to give such an ability to a new hero? Since the souls were removed for reaper. It could cool to have a dark opposite to mercy (evil twin sister anyone)
