Nov 14th 2007 4:01PM Its not a case of siding against other trolls.
Horde trolls are darkspear tribe trolls that swore allegiance to thrall after he saved the tribe. They are long exiled from thier own homeland and near extinction.
Darkspear trolls arnt the only tribe. To be exiled means other trolls drove them out and exiled them. If it was other races they wouldnt be 'exiled' they would have been 'forced out' or 'driven out'.
Why are the trolls against the horde? Why not... the trolls that are with the horde are the darkspears and therefore considering they are exiles, why shouldnt they want to wipe out what rampaging murlocs started?
