Skills and Super Ability of the Orcs.

Orcs are the greatest race!!!!
The more you play with them, the more you realize that almost all skills are good for them. This is very convenient.
Plus, they have good creature growth and a very fast start.
The most important thing for them is to always take Attack (Retribution or Fire Arrows. For Krag, you can take Powerful Strike or whatever it's called), Leadership (Empathy is a must, choose either Aura of Swiftness or Inspiration), and Logistics. The rest is up to you.
But first, you need to upgrade Blood Fury, then Support, then Remembrance of Our Blood.
Machines are simply excellent. Then it's better to take Fire Arrows. Neutral creatures are easily defeated, and enemy heroes will have problems. This is almost like having an eighth unit on the battlefield, which has 1200 health, excellent defense, and three shots that deal +150 fire damage with armor penetration. They work very well with artifacts that increase luck or with the Luck skill itself.
Luck. An excellent choice. Double damage for a race that relies on strength, not magic, is a real gift. Plus, there are great sub-skills. And Soldier skill – especially for Executioners, and Magic Resistance (Orcs are vulnerable to magic).
Defense. A very useful skill for Orcs. You're wrong to say otherwise! Orcs are already well-protected from physical damage thanks to Fury. And with this, they become simply monsters. And Fury sometimes runs out...
I think that against Humans and Elves, you should definitely take Defense. And, of course, Defense against ranged attacks.
Education. A useful skill. But I'm a little disappointed in it. The real benefit from it is less than it seems. You shouldn't take Fury of the Blood! In most cases (especially against an aggressive opponent), it does more harm than good.
War Cry. A very useful skill, but it rarely appears. Fury of the Horde, Frightful Howl, and the War Cry that increases morale and speed are especially impressive.
Darkness Negation. No matter how much they say it's not very effective, it's better to take it against a Necromancer and a Magician. At least because it will no longer be possible to control Cyclops. And that's already a lot. Plus, the effects of spells will last much less time.
The Super ability is good, but no more than that. 500 Fury points are useful, but they tend to run out quickly. Plus, it's not the best development in Machines, and not the best development in Attack.
