Vol'jin himself is there to end Zul. Along side Vol'jin stands a figure thought dead to Zul, Rastakhan. Rastakhan finally realizing that if the trolls are to be strong, they must stand with the strongest. Without Zul's prophesies filling Rastakhan's head he was able to finally see. The Darkspear have always been the strongest, it was the darkspear that stood against the troll tribes time and time again( with the aid of the Horde and yes the alliance).
With the Revantusk tribe( Amani ), Shatterspear tribe ( Gurubashi Empire) along side the Darkspear, there goals are the same as the Zandalari only the opposite. The darkspear want to hold on to what is left of the trolls peacefully and not through war, thereby bringing all races upon them, leading to the trolls defeat and with that Rastakhan serves the darkspear now, along with those who followed him.
If blizz decides to make race skins with the new models this would allow the horde trolls to make an amani( Revantusk ), Gurubashi( Shatterspear) and Zandalari, along with the darkspear skin.
Can only hope for something like this to happen.
