Cy the tip guy says:
Please communicate respectfully with developers during the beta period! Give feedback without being disrespectful, up vote feedback you agree with and overall, help shape Modern Warfare. WE are the voice of the game and the potential change. WE can change the game by giving constructive criticism. Avoid being uselessly toxic, regardless of what you feel should or shouldn’t be happening. This is the most important time of the year for us so let’s make sure we get the game we all want!
