I've a few questions
What is stopping players from obtaining rewards on non populated shards and shipping them to populated shards and so decreasing the value of the rewards like they do with powerscrolls?
What is stopping everyone from joining the same side in order to win the rewards? For example, in factions people would join different sides to fight without reward, in this VV system, the winners get the reward so say Virtue has 20 people and Vice has 3, why would a player join Vice knowing his team will never get the rewards?
