Umm I have the exact same types of returns on Ark, RT, NI, Toulan, Cyrene etc. as I do on Calypso, so not sure what your getting at with that one comment about calypso loot being worse then other places. I have never gone to Arkadia or any other planet for that matter and gotten sustained great returns it always goes up and down everywhere I go it is no better on one planet to another after awhile. Calypso just is so much easier to sell the junk you get compared to other planets hence the biggest reason a lot of people stay here I think. As I stated in other threads I can even sell Arkadia or RT materials faster on Calypso then on their native planets.
And Space just sucks to deal with to get mats back to Calypso and others would agree, so that also keeps most people on Calypso. The planet to turn around the fastest loot to keep people going is the planet everyone will stay on. MA and PP's can't make this happen only players can, the creators give ways to dump mats but not make markup off of them and it is all about making Markup off mats.
