My group has played about 4 times now with 5 players and every time it feels like the double agent is bored with very little to do. While still in their hunter role they have to play the part or else be caught. Once they are an agent character they do next to nothing any attempt to fool the hunters has never paid off. Is there an element to the strategy we are missing?

Does anyone play with house rules that help that player have something more specific to do? Allowing both agents to score objectives, however all 4 objectives must be scored and both agents must escape. Giving the double agent (hunter version) knowledge of the location of the objectives?

We all really enjoy the game but whoever gets that character seems totally unsure of what to do.
