ummm try not to double shot so much only do it when appropriate. sometimes not double shotting could win the battle, but if you have mid shields by all means double shot.

ima keep it real and say u should just wait for Halo 3

you seem generally confused...work on knowing when to back off

You just need to listen to the people whom posted before me but if you need it I could help you with hands on training. If you want help my GT is Soulful Slayer

Your trying. Awareness. You are running into the ring and not looking around. I always assume there is someone in the ring. Running in and not looking around gets you assassinated. Communication can help with this but if your teammates don`t talk you are going to have to be a paranoid player, once you kill or shoot at an opponent the other team will be coming for you. Double or quad shot can get you through if your good with them. For you I would say work on timing your nades and announce to your teammates where opponents are so they can back you up.*** I would recommend you work on Awareness before you try to master you double shot or bxr.***
