I always thought Renekton needed AD to be effective.

He really doesnt. He already brings armor shred, has good base damages, and if you cycle his rage correctly well, you see what happens. Though playing Renekton like an assassin for carries is pretty fun as well

he does. his base ad isnt really high at all. most of his damage is from bonus ad. are you saying you need ad to do damage or be effective?

i usually go full ad on renekton because its fun to one shot people with him but hes pretty useless after 20 minutes nowdays unless your really really ahead
