How do you lane against renek?
This mf doesn't give a shit about your tower. I can't get near minions when I play against him. What do I do?

Freeze the wave and build this 

But yeah, laning vs him is god damn awful on a lot of champs
Mostly it's just rushing a chain vest and tabis, tbh.
That, or play Quinn and enjoy fucking him over if you have half-decent E timing.
It can depend heavily on your match up. Are you fighting or defending? Playing for early or late?
Most of Renekton's abilities will force him to push the wave. So as stated before try freeze it infront of your tower and buy
He is extremely powerful 1 on 1. If your squish - try avoid fighting 1 on 1.
Strong early - Take sustain runes and prepare for the late game.
Play kennen, urgot, vlad or lissandra
Play Nasus
