wow I see people complaining about goblins.... look, goblins aren't specially for fighting, their great numbers make them a "pest" for the enemy, specially large and slow ones.
For example, Fighting against Baal, they are useful. They are fast enough to get across without dieing, so when they completely get across him, baal will start attacking them while not facing your side. So, it will be time for your strong troops to go safely.
Goblins also kill archers very easily, as well as the cannon.
