Tutorial how to get valour:
When you see other ppl outnumber the enemy,just come close to enemy and let others kill it you will get 5 points in score for that. Much more then for a kill.
Repeat this process,you can also help ur teammates when they don't need help and steal their points by trying to wound and steal kill. And this is my frends how you get valour. If you shot with crossbow someone you will get 2 points or even one,but stand near ppl who are killing = profit.
So you still think valour is some cool thing and need to be tracked?
