So I was Renekton vs Nasus
Being his counter, I was able to dominate him pretty easily. Right to the point where I'm around 100 or so cs while he's at the 20s. Took out a turret, proceeded to keep going with some cash in my pockets, took out another turret, and the jungler Xin Zhao finally decides to come help the last turret. Although he wasn't able to do much.
The Nasus left with 29 cs with a score of 0/4/0
And before you say "ER MA GERD YOU SHOULD'VE HAD HIM AT 1 CS WITH 0/100/0!" I'm low elo.
I didn't report the Nasus cause I can understand the frustration of being completely countered and dominated with no help from junglers or other lanes.
So my simple advice is: Gank at least once. Especially if I'm constantly in front of the enemy turret with no wards whatsoever. And still going. And going.
