I know you can kill non 3 point clan targets in the favorite list, but there's been a lot of shifting back & forth as clans load up member & shift up/down. It would take a lot of list management to keep the 3 point section current, whereas either list sorting or an extra symbol after the "C" in the char name to indicate 3 point status would be more dynamic on the system side.
Is this just a lazy request?
PS - I can also see the implementation of this feature making clan fighting much more dynamic as you fight harder for points status and to nail people who can give you more points.
