Its simple for me. I kill all mobs appropriate level of the strike quickly and efficiently. What's the point in standing around after you kill a mob. Quick search for ammo and move on. I get most of my items from drops. If its green and I see it I pick it up. If I missed it oh well. If I see a blue I get it. If not it gets mailed to me. There is a way to clear everything and still move quickly. The strikes aren't hard to memorize and the mobs don't switch it up on you. In the end efficiency is in the eye of each of us as an individual. I'm not there to dixk around but I'm also there to maximize my loot output
