Can you clarify what you mean by no DPS. Do you not want to do any damage at all? No meleee damage? It is kind of hard in this game to advance without doing any damage. Support is great, but each player can support themselves mostly health wise. If you want to set up combo fields it is tricky to time things right unless you are with a well co-ordinated group.
