60% of damage is 6000 rep base, double that to 12000. You'd need to do like 14min kill with 60% total damage for 1k rep a round.

Do you understand how baseless statements like 'I do xx, or xx' can get blown out of proportion.

The bigger question is why use someone like Khan when giving Lance the same gear and runes even without saints/stars will increase your overall damage every round.
