Flaw in the whole sit back and farm when you are behind strategy...
I told my level 12 friend that when you are behind to just sit back at turret and farm. His favourite champion right now is Irelia and honestly he does pretty well with her most of the time. Any way this nasus got 2 kills on him this one game and I told him to sit back and farm under tower.... Nasus dove and killed him under tower 4 times, first time with a gank and the rest were him all by himself, he tanked like 12 turret shot and didnt even lose half his HP. The towers in top lane cant defend you when you are behind :/ something needs to be done about that in my opinion.
