There isn't much to complain about in the Destiny beta. However, as they iron out all the kinks , which are very few, I'd like to point out that during Crucible matches, when two people are in a gun fight, sometimes they kill each other. That's not supposed to happen. This is a similar problem that Battlefield 4 had before their netcode patch, which was an issue with the server refresh rate being too low. Hopefully, bungie can see this and fix it in the actual game.
