CvC Quests suggestion
Something which I liked about the Clan Quest system is that it allows players in the clan to specialize and focus efforts on specific areas. I'm one of the few in my clan that actively participates in 3v3, for example, so I tend to take the tag arena quests.
I think it'd be a great addition to CvC. Keep it simple - use the exact same mechanic as the Clan Quests, however, instead of giving people three selections, limit each player to just one. Have the completion reward a substantial amount of CvC points.
