Heroes protect the Systems!

I would really like the Heroes in ES2 to be more interesting when assigning them as governor to a System. In EL they helped defending the settlement when it was attacked and even provided some boost with their Trinkets. I know there a skills you can unlock to boost some defensive stats of the system on some heroes but it would be so much sweeter if the Hero would actually help out by providing a significant boost in Ground Battles.

Maybe even hopping into some Mech or other device and lead the troops!  You could add diferent weapons and Armor or Armyboosts like you do with all the ships. I just think sieging and fighting in ES2 is way to dull the way it is now for such a great game!
