Excellent tips there.. made me laugh as well.

Here is one tips that ppl dont take note off..

Ears.. you have 2 of them, listen where ppl are coming from and how many footsteps you can hear. This is vital in a clan match. If you can crouch low (against a wall is good) and hide away, listen for where they are coming from and where they are going. Once you have an idea which way they are going let your team know, always better to surround the enemy and take them down, than you take just one of them out rambo style.

And as Loaf said, its a team game. Make sure in matches you win as a team.
