F.e. A player/unit has to belong at least a month to the faction and/or has earned an amount of loyalty-points to wear the faction-insignia.
At the moment there's no reward for being a loyal house-/clan-unit. That decal-thing still wouldn't be much of a reward (nothing compared to what those faction-hoppers get), but at least it would be something. I think it would be nice for those who stick to their house/clan, if they don't have to see faction-hoppers wearing their faction-insignias...
