No for me. Broke ex-heirs appearing with elite armies that are much stronger than their old armies (before all their possessions were taken away by the conquerors).

It's CA's lazy way of saying "challenge" . If it is better implemented, sure. There has to be a reward system (which is lacking TW games, aside from the Senate Missions in RTW).

For example, if an ex-heir can assemble that army, there must have a hidden resource. If a player destroys the army, then all their hidden resources will be turned over to the player (i.e. the reward part).
