RNG favors you then. I, on the other hand, head back to the tower with the two blues from the end roll (I do actually kill most of the enemies except for the ones in the beginning of the Mars strike. I was defending those with the logic I'm about to impart on strikes because of the RNG) and maybe one from the kills. I got my exotic helmet from the two exotic engrams I bought from Xur. So, while the RNG is nice to you, it is a complete a$$ho£€ to me.
