“Heroes of Might and Magic V: Tribes of the East”

2 Olga: The Cyclops will throw goblins only if their unit is standing on an adjacent cell. When hovering over the enemy, a throwing arrow will appear; no additional buttons need to be pressed. Shamans with a chain also kill adjacent goblins to gain mana, so lightning charges up quite quickly. In any case, one goblin is consumed from the unit.

As for the Barbarians, the creative possibilities won't just end; this is the last add-on for the 5th installment, so they won't need any more. However, you are wrong about the idea that it has been exhausted. You seem to forget that the add-on not only added one race but also doubled each existing one. And that, if you'll excuse me, means 56 new monsters that still needed to be balanced.
