Not my first B.Net account obviously
I wish my teammates played more passive at times.. During the start of the game you obviously want to be aggressive to get power weapons and map control, but if you fail and you're all 4 dead let's say on the map construct, and you spawn down low, just wait for camo to make a push. My teammates never understand this and they just keep on rushing up the lifts and dieing. Now maybe you wouldn't have to give up right away that early to wait for camo, but you should know when you've given up enough deaths for you to wait.
