I had base luck of about 850 plus honor. So about 1500 to 1800.
But i farm a lot there with this setup and i got never so many drops in such a short time. Usually i get 1 arti and 1 armor part in about 1 hour.
The armor parts are 95% pack drops, just a few spawn in corpse (and always in the same position in EC grid). The ML-Artifacts are always pack drops.
