No dupes, obviously double D Zaerog gets as much love. Otherwise, DL Fagan hands down. I have hypermax DL Fagan best friends so your Fagan may not get as much attention. Your double D may get a good deal of love if you choose to be one of the very select few to actually max-skill him. On the other hand, Infinirog is gonna come, might be better to focus your resources on him instead of max skilling double D. No matter what, DL Fagan will always get considerably more love from your friend list, since damage is literally the only thing that matters in farming.
