I don't really care about the loot either, nor do I care about getting there first. I do care about playing as a team. If it takes a couple of minutes longer, so be it. Usually the only reason I run them is to complete the Milestone. And that's easier and faster when three people work together as a team. The way they were intended to be played. I don't know if you saw it, but there was recently a post wherein someone claimed they preferred to stay back and kill all of the ads rather than run ahead with those who left enemies behind. I agreed that leaving enemies at your rear is generally speaking a bad idea and tactically unsound. Even in a video game. I don't like doing that. That said, it's more important to stay with your teammates. "Where we go one, so shall we go all." The best weapon, piece of gear, or whatever that you can possibly have - is the person next to you. And again, in my opinion, it's the same way in video games. We're not talking about an activity that can sometimes end up lasting hours which should only take a fraction of that time as long as everyone knows what to do, when to do it, where to do it and why they're doing it. We're talking about Strikes. So why run ahead of the other two. It's selfish behavior, pure and simple. Poor sportsmanship. You name it. There is no denying that. Sure, there are those who will try and justify it but it remains selfishness nonetheless if they're not alone. However, if one is alone then certainly, they're free to do whatever they want.
