Dunno if anyone keeps up with RIGs these days, but the latest scheme is gatcha RIGs.
Basically, if you get like... 25%, 50%, 75% and 100% of the items from the RIG, you get extra stuff.
Kinda scuzzy... really drives up the prices of stuff (even the "fail" stuff) in the MP.

BUT THAT'S CLEARLY NOT WHY I'M POSTING!!!
I just found out that (in a strange act of benevolence) the latest gatcha RIG has free itemz!

Free is free, man. I ain't gonna complain.

(also I like how "ain't" doesn't get the red squiggly of "you spelled this wrong" lol)
