Phew - check the Tactics part of this thread (3rd post I think). Basically one person needs to slant one way and the other slant the other way to make the enemy have to decide who to face. The person he faces defends while the person he turns away from takes the shot.
I think you are used to fighting solo which means you're not anticipating having support....but yeah I was tired at that point so I was probably sloppy too - we looked pretty rough there
We'll work on that.
Great having you man....glad you're enjoying yourself.
