If a unit's Might is below 5, what classification does it fall under?

When a unit's Might is below 5, it is classified as "Not Mighty." This classification implies that the unit does not possess significant strength or offensive capability to influence the course of battle effectively. In the context of the game mechanics, units with a Might below this threshold are likely seen as less impactful than those with higher Might, which enhances their effectiveness in combat situations. The term "Not Mighty" neatly encapsulates the idea that these units lack the requisite force to be considered strong or formidable.

The other classifications such as "Weak," "Common," and "Average" may suggest different levels of effectiveness or strength but do not directly denote the absence of Might in the same definitive manner as "Not Mighty." Therefore, when considering the explicit threshold of Might levels, "Not Mighty" is the accurate designation for units falling below 5.
