Every Ork will tell you that no-one likes a show off. If a mob starts struttin’ around Mektown like they own the place then other mobs will be more than happy to take them down a peg or two by attacking their fort. They won’t attack just to get more scrap or rescue one of their boyz, they will attack to humiliate the swanky mob and show them just how un-Orky they are.
