Theres lots of stuff missing from the game (The Followers for example were supposed to have 3 skills to choose from. What the hell happened?)
I'm not sure if you're talking about something else, but the followers all have 4 tiers of abilities, each with 2 options. Higher tiers become available with level, and you can retrain them at any time. Just right click on their unit frame.
