Most of the people I run into on patrols I help, and they are pretty good about returning the favor. However there are a lot of bad eggs in the Tower that make it hard to be nice. And I feel for the level 30s. The first one I saw on PS3, I approached and waved intending to congratulate him. As soon as I waved, he melee'd and shot at me like we were in the Crucible until I walked away.
