You do not get more due to the playlist, you are using confirmation bias to make your judgement. You get engrams fomr everything at the rate of random. Please though continue to attack my character rather then the argument, I too get my marks increadably fast but you know, part of that comes from playing a bunch of strike over and over due to the good rewards I recieve from playing them and playing them fast. Rushing through means you kill what is neccessary and nothing else, or little else. You get plenty of drops on the way to the boss doing this as well as the end and you get through many more. If you want a better idea, get some people of both play styles to record themselves and see how the drops fair, but I'll tell you, you don't need a strike to farm mobs and you are only slowing others down who want to complete the strike. You make so many assumptions but only show your own trerrible nature in the end.
