Hip fire is really effective but it depends on the gun. For example I could get tons of kills hip firing a hand cannon but not the pulse rifle. Naturally it's not as accurate as halo since all guns have ads. Some guns are meant to be hip fired and have "increase accuracy when shooting from the hip" on their skill tree Melee is EXTREMELY satisfying for all classes in Destiny. The other dude already answered your question. The highlight player option brings up a menu that let's you invite players to your fire team, view their PSN/Xbox live account, or look at their gear.
