I see almost all cap-whores posting here about good and less good reasons, but with obvious passion to cerbs in their hearts.
Wtf you need reasons for? It's a game, ffs. Just tell devs you want damn cerbs back. It is their DUTY to make you happy. In case they have no time to make you happy, then pls step back and let others go in and do the freakin' job. Why is every dev so afraid to pick a young apprentice from the crowd, show him some tricks and leave to have a rest?
But... don't expect massive battles just because YOU will get what you want. Only getting and keeping new players can do it.
