I love this build, but I prefer One in the Chamber the most of time. It deals more damage and with it I still can take creeps (in Sculls, for example). Only minus is that you should be able to play faster (2nd-auto-1st-auto-3rd-auto-ulti-auto, for example, in 1-2 sec) than with 2-1-auto build, but here we have 100+3*80=340% dmg instead of 250%, and faster firerate. It's sad when 1hp enemy kills you because of 3sec recharge :) In this case you just can't fire-and-forget, but overall dmg is...
