I've gotten plan c, the last word, mida, and suros (in that order) All from ROC strikes, but I've done way to many ROC strikes. I've gotten about a dozen legendary ships, also got dragons breath from a legendary engram I received from an ROC (2 hours after buying it from xur). I've gotten tons of legendaries from engram's. I was most excited getting mida & suros, I got the suros a week before it's damage was gutted in the 1.1.1 update
