And we are back with this "I earned it" shit. I got my 310 ZS thanks to an engram the warpriest dropped, I was lucky enough to get it when I decoded the engram, my friend (who got a primary engram as well, wasn') it's just luck. You didn't earned shit. Let me give you an example of earning something; You EARN the exotic sword after COMPLETING the sword quest. You were just lucky that you got it as a droop. I am happy that Xûr is actually selling it, because my friend has been griding for that shit and never gotten it. It's a great primary for pve
