THIS is the danger with letting things slide.
Take this perspective tho Dennis. As soon as Leon became finishable he hit his comeback perk. Which he shouldn't have, to avoid the wake up taunt. K.D used that comeback as the wake up taunt and hits his finisher which is what would have happened if Leon hadn't have hit his comeback button.
Now does a champion have the right to hit comeback right as they become finishable? Yes but this falls under ethics.
Does KD hover in hitting this finisher right away? Absolutely, anyone who disagrees is doing way more damage than good.
Leon and KD being both vets decided that the finisher was fine under the circumstance. So all was washed and the finish stood. That's what happened based on what I saw.
