To put another example: GvG has less monthly players than FA/AB, however paradoxically it has his own title, special drops from strongboxes and the chance of wining capes for your guild. While in AB/FA people are just left with "fun" and nothing else, idk, i dont see this as positive to the game call me weird.
PD: Sorry for double post xD
PD2: Hunting/competing for something can aslo become fun, aswell as brining more players to the mode or mantaining it alive.
Anet: nothing is gonna happen, we even got a costume away 6 years from the shop and no1 cared.
