I would like to suggest a couple things:
1. There needs to be some type of information on splash screen downloading into the servers to let all players know about the Buffs and debuffs. In our events too often I hear of new players not knowing they are hurting our team.
2. For out of formation players, I would say they should have Sprint disabled or greatly reduced to say 25%. And I agree with Bradley where when we spot out of line enemies we always count them as free tickets to drain the enemy.
