But you only get like 1 sometimes 2, and you can only get it maybe 4 times per minute on avg. But if you just run around killing enemies while grabbing the chests/SM. You can get engrams too. You can get up to 4/5 SM from 1 engram from enemies or from the chests. So why not make the time worthwhile? Also leads to more glimmer, weapon parts, armor materials, strange coins, motes, etc.
