Disclaimer: bottom right few heroes were NOT in the calculated version by DotaMetrics, therefor I did not include them. If/when DotaMetrics recalculates these farm dependency heroes I will redo the layout.

In Who is the Most Farm Dependent Hero?, I attempted to measure CS scaling. While there are some issues primarily rising from the small sample size, shifts in how Normal/High/Very High play the game, and emerging trends during 6.74 (Bounty Hunter is likely too high, for example, and Tiny is likely too low) Iâ€™m generally pretty happy with how it turned out.
