Don't worry mate. I didn't mean to come off strong or offend you. I know how to play karthus and also there are times I will suicide for my team in order to inflict as much damage as possible and also slow the enemy with my wall. His Q does double dmg to single target. Also my csing is decent but could be better. If you look below Bjergsen the #1 mid laner in NA has 7-9 cs/min depending on the champion. Mine is 7 right now on average with karthus. KPA isn't everything either, I manage to pressure the map and take camps from the opposing jungler such as the wraiths, and scuttle. Although I appreciate your coaching, I don't need it. This post was simply for lulz incase you couldn't tell
