There's literally no logic in giving him this crap at all. Renekton himself already does severely impressive damage by himself, having the ability to land a strong 2-3 seconds stun which gives him enough time to land his full combo before dashing out, especially when coupled with either PTA or Conqueror. Either playing a long-ranged top laner or someone with a shield is just one of the best way to counteract against this, and Riot chose to kick out one of them.
This is just utter ridiculous. Top lane is already a giant shit-hole, and your solution is this...?
