I suggest that the battle/war team challenges have an element of boosting players scores based on how much they contributed to the team challenge. I feel I contribute too much of my time to these while others are bettering their scores and so I think those that help and contribute to the "team challenge" should have a boost to their personal score. This would possibly appease those that help with the challenge and feel like its taking its toll on their score but may also encourage those that don't help to help, hope that makes sense. If not, then maybe a seperate board showing who helped in the tasks so we can all see who is doing it :-D
