After gilneas questing the worgen should of went into silverpine to fight back the forsaken so we could at least see the rest of the worgen lore and it would of ended in a lose but at least it would of been exciting.
After silverpine the worgen could of gone to hillsbrad foothills to fight and save southshore and fight the forsaken there and they could of fortified southshore like they did with sentinel hill turning it into a giant war zone.
They should of added a multi-passenger mount for alliance and horde, horde would get the 4 person goblin car you see on the goblin starting zone and worgen would get that horse driven cart holding 4 people on it the one from the worgen starting zone and the one in western plauglands.
