I don't get why people hate on hunters using melee. It's one thing to walk up to a boss and smack his legs then die, but you can use it properly. In Crucible the combo of a Blink Strike and shotgun to the face is hard to argue. And on strikes, use the environment, you can still hit enemies that aren't in line of sight with Showstopper if they are still in range, lets you do several thousand points of damage on bosses while safe in cover.
