Expert take
Renekton is an excellent champion for players who want to impose tempo instead of reacting to the game. His strength does not only come from dueling, but from his ability to create moments where the opponent must answer immediately: wave under tower, level 5 dive, empowered W on a key target, Herald rotation, mid-game flank. He becomes far less impressive if you only play to win your 1v1 without converting. A good Renekton does not try to prove he is stronger at all times; he uses every Fury window, every wave, and every enemy cooldown to move the game forward before his natural impact drops.
