im guessing since you start in a spec already at level 1, there is no need for the bot to have the option anymore. it was only there to select a spec at level 10. unless something has changed, you have to exit the bot in order to change specs in game or it wont use the correct rotation. if you want to level as outlaw, just wait till you can change specs then load the bot as outlaw and then let it chug away.
