Quick Disclaimer: This all happened on Test. I'm not familiar with how Test .vs. Live works (minus new content), so it may or may not be valid on Live as well.
I was two-boxing in Droga, with one character stationed on the NW area killing for names, and my other toon stationed on the NE area where names are listed...essentially, the two locations mentioned up by the picture.
I never had a single named spawn over 8 hours of camping on the NE area. However, I was able to get most of the names in the NW region (including Dronan) to spawn multiple times.
Copper Hammer is still his common, and the Maul his rare. If he has the maul, he will not have anything equip'd.
If you're wanting these items, it's honestly just a long camp. My toons are 105 and 95, so needless to say I didn't stay still.
Bonus: extra tribute items, and with speed killing constantly, pulled in about a few K per spawn cycle. Not too shabby considering what I was there for.
Hope this helps future farmers.
TL:DR- Camp the NW corner, plan for a possibly long camp.
