Your favorite Campaign Farming Build? (HC viable)

Hi folks!

So for, for myself, it's been the Deathguard Reaper from the Top21 List. Can't say it's HC "friendly" due to the insane amount of reflect damage you take and it's a bit squishy vs nemesis, but that is mitigated by it's mobility, kill speed and ability to hit & run.

What build do you enjoy campaign farming with?
