I had a slightly simpler approach: Y''Shaarj - Balinda (with water elemental) - Tirion. Started the Lord Banehollow bounty in Felwood, at the first encounter killed all opponents except blood imp (who then did nothing except buff adjacent demons for the rest of the encounter), and then used Balinda to knock my own characters' health down while Tirion pumped the blood imp to the point where it could survive three hits.
