I was late for the party with the Contest but it made me think about the variety of the Stonekin.
Other factions have humans, dragons, ancients, beasts and many more, but Stonekins are all elementals with metal body and blue flames.
So I thought it would be cool and thematic to add Giants, Skanes and also mortals, who stayed loyal to Giants.
And I present the Giant's Supporter
Abilities:
Giant's Supporter - If this unit is within 8m from an XL unit, its attack can knockback small units.
