Navigator with Primordial is my main farmer - put him with GCOTD (with Primordial) and say Gunner Lilith or another team hitter and you should be fine...primordial does make it quicker and safer in all levels. I am now using this team in nearly all batle types out of PVP - I even have my third set of primordial on my Cybork and have him as a ride along trooper - seems to me that ride along primordial also add to your golden buffs but not 100% sure on that.
