Get Corrosive on your melee with the Exposure arcane. Heat viral on the weapon. You want to increase base damage for the incarnon mode. The range on this is amazing and will hit everything including drones. Increasing critical damage is an option though this kills almost everything in Steel Path in 1 or 2 hits. Then heavy attack anything that is a boss and you wont care about the 2.6 CD. Not a meta weapon but Very very good in both incarnon and non-incarnon modes.
