[ONYXIA] 20 gold as call to arms reward

Hi, i wanna know if it's correct that u receive 20 gold as a reward for call to arms when you play a battleground , that is blizzlike??
I ask because everytime we, pvp players enter a battleground with call to arms event, there re many players entering with different accounts just to farm gold, they even stay afk and do nothing. Instead of the weekly event having more pvp action in bg, it causes there to be more afkers gold farmers. Making the weekly call to arms horrible for pvp players who enjoy battlegrounds.
