Absolute skills

It seems there isn't a dedicated thread on this topic, at least not explicitly, so I decided to create one. Let me introduce myself: "I'm a rather mediocre player, although I can defeat my friends. I became curious about why these powerful abilities are even needed, even though my acquaintances insist they are great." Now, the main question of the thread: "How necessary are they?" My reasoning: 1) Orcs. The special ability grants 500 points of rage at the beginning of the battle. As far as I know, it's already possible to accumulate rage quickly in serious battles, but what's the point in easy battles? 2) Demons. Okay. The special ability allows for lightning-fast summoning, but the gates already open quickly, plus you can take "fast gate opening" from the "logistics" branch. 3) Humans. Scouting becomes twice as powerful, but what's the use? 4) Necromancer. A quite decent special attack, but there are analogs: "haste (general)" and "slow (general)." 5) Elves. They already have a high chance of success in almost every attack for archers. Is it really worth the effort? 6) Dwarves. I can think about this one more. 7) Dark Elves. Chain damage is doubled, but by the time you upgrade this, you'll already be almost overpowered (sorry for the word). 8) Mage. Why does a mage need so many spells? I don't see the point, because you won't be able to use that many in one battle anyway. You can, of course, diversify each battle with different spells, but how much benefit does that really provide? Postscript: "And valuable skill points are sometimes spent on unnecessary/marginally useful talents." I'm interested in reading other people's opinions on this.
