I'm a completionist. I'm not talking about the trash enemies at the beginning of sepiks prime strike, I'm talking about groups like the vex and minotaurs on the way to the archon priests once you get on the pikes. Why people skip those is beyond me. A legendary or decoherent might drop. This is why I level up the cryptarch every 3-4 strikes with decoherents. I kill everything in a strike.
