I have been hunting vixens for a couple of months with my [Sollomate Mayhem Azuro, Adjusted] as suggested by others in the forum.
So far here are my results according to Entropia Tally.
Total loot 14421.44 PED
Total spent 15300.07 PED
Returns 94.26 %
3% average Vixen Gears = 1704 MU from gears = 825 PED profit from just gears (I sell the gears often and don't really keep track, but this is an underestimate at 3%, the loot ratio is given to me by the tracker)
Kill count / Loot Events133482
I started around level 5 laser sniper and am now level 43 hit and 39 dmg, I went from level 1 animal looter to level 19 so far.
I am on stage 4 of the color of envy, with 72000 / 102400 kills and hope to finish the final stage before moving off of vixens.
Also I can sell a lot of the other loot for 110% to my society leader and loot other high mu items often.
I have also been doing the AI mission while I am here, and have 28 [Presidential Pay Stub] out of the 260 required.
Did you know? When you have 260 [Presidential Pay Stub] you can refine them in a standard refiner for 5200 rockbucks total! (20 each certificate) That is an additional 52 ped of free loot that can sell at an easy 500% mu for an additional 260 PED at the end of the year, funny how that works out.
