Forced action modifiers

A special form of CC, but equally powerful, are the forced action modifiers. These force the target to do something, temporarily rendering the player's input useless. Specifically, taunts force the affected champion to attack the taunting champion, while flee causes the affected champion to simply run away in the opposite direction for the duration.
