I permit me to post a build gvg witch turn in my head since a few month...
Before saying anything try the sin with strengh of honor and judge's insight, that's the best spike i ever see.
For the flag runner i choose a defensive player who run really fast and spam spirit at every return to the base.
Ranger can play incendary arrows if you prefer.
Monks can be change if you have favourite skills.
