If you are looking for other things along those lines then I got another that just hit me while I was playing. Handing in engrams if you have a legendary and a whole bunch of blues. Hand in the legendary first and then quickly hand in all the blues. I get tons of blues turning legendary when I do this. What I do exactly is keep legendary engrams to the side. When I have a whole bunch of blues I take one legendary to open first before all the blues. Then I hand in the legendary first and then rapidly hand in all the blues.
