The only thing I can say, is save up your engrams (I usually try to do at least 15 at a time). Before u turn them in apply everything u have w/ the highest attack and Def maxing out your light, even if it's stuff u don't usually use. Take them all to the cryptarch and spam the -blam- out of them, don't even try to look at what u get just hit the -a- button as fast as u can.
