There'd be far fewer complaints around here if people would play by this. Bungie sets limits to what you can and can't do (I'm not getting into cheating, that's another situation), so talk to Bungie if you think it's wrong. But don't blame people for playing within the set of rules given a different way than you do. Personally, I get frustrated with people who just can't seem to apply strategy in the fishbowl boss fights we have now. Take out adds, hit the boss, take out the next wave of adds, attack the boss. They'll be standing there ADS with a sniper with 10 thrull swiping at them. But then I think they may be kids who just don't know better, or adults who just don't know better. Or they really could just be people who want to rush and don't care. At any rate, I've grown pretty used to seeing "last guarding standing" during a strike and just make sure I'm playing the way I know will have the best odds of success in a reasonable amount of time.
