mages versus orcs

What's the actual problem with killing an Orc in the late game? For example, if you play as Hafiz against Haghesh and have Knowledge at 40, it's a minor artifact that gives all your troops 40% initiative. Goblins will move before Centaurs. And in general, the entire initiative scale will be in favor of the Academic. Assist with Goblins, Mages, and Titans targeting a single unit. Haghesh's Centaurs will move once, and then be blocked by Turrets, with a minor artifact that boosts HP and defense.

The problem is that you might not even be able to create the artifacts; you might not have enough resources, and this depends on how long the game lasts. Also, the leaders and the hero have a great ability that speeds up the turn. Therefore, the Centaurs will move more than once; with Wrath of Blood, they will tear through any stacks of Mages, and a well-developed Ballista with Fire Arrows won't let you relax. A Mage can be saved by Darkness, or Chaos with Pyrokinesis. Well, it also depends on the artifacts and spells. Hagga at level 25+ is overpowered. I have an Orc player friend who only plays as her, and no one else. So I know that Orcs are very difficult to defeat. In general, you need to take units with high initiative and Darkness or Chaos, and they need to be very strong.
