Your Reach autos are your main clear. You're rushing Rage for crit so try and hold ult until you can back with 2k gold to buy Rage. You should be able to guarantee a Rage stack with your first ult
Farm for Rage on first back. Play for rocks at 3 your clear is very good because of the extra reach on your 3. You are "auto based" but you rely on your abilities with reach to make it work. Use your taunt to set up Lernaean for max damage.
