In game, it seems that any champion that chooses to go the path of the governor should be able to build roads, this is not the case. I looked at the code:
<AbilityBonus InternalName="RoadBuildingAbility_Level">
<AbilityBonusType>Unit_Level</AbilityBonusType>
<AbilityBonusOption InternalName="RoadBuilding_Level">
<DisplayName>Road Building</DisplayName>
<Description>Allows the unit to build roads</Description>
<Icon>Ability_PathOfTheGovernor_Icon.png</Icon>
<GameModifier>
<ModType>Unit</ModType>
<Attribute>UnlockAction</Attribute>
<StrVal>BuildRoad</StrVal>
</GameModifier>
<Cost>10</Cost>
<Type>Army</Type>
<Prereq>
<Type>AbilityBonusOption</Type>
<Target>Unit</Target>
<Attribute>PathOfTheGovernor</Attribute>
</Prereq>
<AIData AIPersonality="AI_General">
<AIPriority>5</AIPriority>
</AIData>
</AbilityBonusOption>
</AbilityBonus>
According to this, the only requirement should be Path of the Governor, however, it isn't working. The only thing new in this code I can see is the UnlockAction which is only used by this particular ability.
