[Gameplay] Renekton's Stuns And Hit Box Bugged?

I Just Played Against A Renekton, And Somehow He Seemed To Be Nowhere In Melee Range, Yet, He Would Still Be Able To Get His Stuns Off When I'm Roughly 400 Units Away. I Looked Up His Range For His Stun And It Should Be Nowhere Near That 400 Unit Range... He Would Constantly Try To Dash By Me, And Then Would Always Get His Stun Off, Even Though He Wasn't Even In Melee Range! Was Also Taking Damage From His Blade Swinging Outside Of The Blade's Animation Range. Didn't Think That All Of These Deceptive Hit Boxes Were Intentionally Done Like This, So I Figured I'd Mention It... He's A Tough Champion To Fight, Just Because His Abilities Don't Seem To Be Displaying Accurately In Accordance To The Champion's Character Model. It's Like Fighting A Melee Champ, That Has A Phantom Range Like No Other... Where It's Seems Like You Don't Even Have To Hit The Champ, Just Be Kinda Close And You'll Still Hit, Even If The Animation Doesn't Come Close... Broken Much? <_<
