Death on the Steppes - Yako's Determination

We’z sent ‘ere to kill dem stupid ‘umies in dis stupid place, but stupid Habblo wants to waste time gettin’ shinies from da horse-ridin’ spikey boyz! Dat ol’ fool iz wastin’ time and da Raven Boyz is lookin’ at us and seein’ dat! You fink dat wen Praag falls dat we’z gunna get any shinies? Not if we’z wastin’ time killin’ cows! Stupid ol’ fool! ‘E’s not fit to be da big boss! Kill dem ‘umies and all dere stinkin’ stunty and pointy ears friends!

Yako’s grievance with Habblo is that he has gone off mission and is making the eastsern goblins look bad in the eyes of the Raven Host. To placate him you will need to join the assault and kill some enemy players to show the Raven Host that the eastern goblins are still in the fight.
