Autotrack has been brought back, but this time it is a bit different.
Instead of a clan bonus as before, autotrack is now distributed between the three classes: Thieves, Rangers, and Warriors. Thieves can now use their sly tracking skills to hunt their foes in cities and indoors, if dismounted, though with less accuracy than Rangers, who have the advantage in forests, and Warriors, who have the advantage on roads.
Track in general has changed a bit with its skill requirements. Each level should now make a true difference.
