Yeah, I don't care about engram drops. I'm missing only 6 exotic armors, and a couple exotic weapons. I earn over 30 strange coins a week guaranteed, and will shortly not even need them beyond using them for maybe synthesis. I get drops from VoG normal X3, and hard X3 soon. 3 weekly nightfalls and 21 or so dailies if I do them all. Plus 21 daily world events. I have absolutely no reason to care about the random junk, when there are so many guaranteed ways to get Legendary and Exotic gear. I didn't even do loot cave at all, because that would be boring as crap. I did way too many 24 lvl strikes on my first character, soloed it frequently (not enough were doing it/high enough level, so it'd start with just me after a while), and have no interest in dragging out run number fifty something. Someone wants to stay behind and kill, fine, as long as they are doing something. If they want me to slow down, not likely unless they seem pretty competent. Otherwise I know it's easier to leave them in the dust to make the run easier. Doing the tank with people acting stupid just makes it that much easier for the tank to shoot you. Going from 0 shots to any is a definite step down in skill. As for ruining your chance to farm their kills from distance, why aren't you jumping on a speeder to catch up? Mars alone would mean you get that whole initial room where you can respawn and kill the mobs, while they would be clearing the 3 bosses and tank for you. Which means you can speeder through that and reach the next spot to get some kills. That means reduced time, which kills your whole theory of efficiency through everyone killing along the way. Because you actually skip wasting time on the tank boss, meaning your over-all kills vs. time has a good chance of being higher if they rush and finish it for you.
