Play against Necropolis.

Sorry, was there a dispute? It didn't seem like there was one... But in general, consider this: despite the possibility of upgrading various units, Orcs remain the most vulnerable race to magic. They don't have magic arrows to kill phantoms, and they can't remove spells (from their own units or others), so in a battle with mages, engaging in melee combat is never advantageous. If you have all your troops defend, you won't even have time to blink before your own troops defeat you. Meanwhile, the Necromancer's creatures will quietly and peacefully wait, observing this pleasant scene. And liches and skeletons will continue to shoot. A similar situation exists with Warlocks and, in general, with any decent mages. The enemy's troops won't attack you first; they'll bombard you with magic.

And what does a dozen duels have to do with it?
