Which race would you add to Heroes?

After the war, they sought revenge and attacked the weakened races! But they need to unite to defeat the orcs!

That's not a bad idea. But what kind of orcs should be added?
1 - goblin - goblin with a sling (like in Allods)
2 - orc with a sword - orc with an axe
3 - orc on a warg - warg leader
4 - ogre - master ogre
5 - mountain troll - stone troll
6 - uruk-hai - uruk-hai captain
7 - old ogre - ancient ogre
