i just notice that , when was lower was getting alot of 4% now at rank 50 starting get alot 5% and seems if roll lucky it .01 better then last rank . not much. but cost more shards . not 100% sure, just what seems like. also did first story mission , got another legendary , firmware update, and went up to .05% from the one had at lv30 ish .
I like loot grinding games, right now at 83/119 items, pretty much one of each color. just missing few legendary colors. and purples. but been trying compare each time get some gear.
