Karthus normally has a significant smaller longest killing spree than his enemy does. Commonly, Karthus takes less damage than Rengar. This commonly reflects different amounts of tankyness; however, it can also indicate that the champion with more HP has less agility and thus is unable to kite away from further damage when poked or engaged.

Karthus often racks up a few more minion kills than Rengar. Champs who on average do not earn much CS normally do not require much CS to be effective. They are capable of scaling adequately off their abilities alone. However, champs with scores of minion kills, such as hyper-carries, usually have to have a lot of items to be useful. In either case, work to do better than the averages presented here to do well.
