Why in my opinion Courage is just op on nasus

So I just played a match, In this match I was fighting an top lane nasus. In this match Nasus didn't care about the amount of poke he was receiving as long as he ran up to a minion hit q got his courage proc all was fine because my one q is the same as the healing. So this went on for a while then I Just started beating him in lane and freezing it. Then I looked at his stacks and he had around 65 by 5 minutes. He was healing so much it was actually retarded. They shouldent make a character like Nasus have all of this early game healing. Now I already know all of these people are going to be saying that "OMG NASUS IS SO WEAK RIGHT NOW OMG NERFING KLEPTOMANCY KILLED HIS ENTIRE KIT OMG" Now I've seen a few nasus mains who prefered going courage over kleptomancy EVEN BEFORE THEY NERFED IT generally this is why in my opinion kleptomancy nasus Was not op but rather you guys dont know how to freeze the lane and poke him.
