All I will say is you should try to CC your HAT team (Healer, Archer, Tank). Are you a Free Player? Read this guide and make it your Guide. It has helped me tremendously over the last 3.5 months.
To answer your question, I would say no. You don't have the Heavy Armors or Healers CC'd/strong enough to get you through conventionally, not to mention the Archers.
