Attitude towards complete anti-magic!

First, it would be good to interpret the concept of "antimagic":
1. A nature spell?
2. An ability of certain creatures (e.g., Chaos Demon or Berserk)?
3. A skill in "combat"?
Depending on this, we need to "adjust" our approach. Complete antimagic simplifies the game as much as it complicates it. Antimagic as a spell is the best option.
A magic resistance skill is a plus that any hero who has maxed out their melee skill can use. Although any hero who has maxed out their skill by 100% is already strong.

The concept of "antimagic" was explained at the beginning of the topic; it's worth revisiting...
In general, I agree with Leshy that antimagic spells are practically useless, and even in battles with mages, they don't always help, and sometimes they even hinder. For example, a hero casts antimagic on themselves and automatically removes their magic resistance. If the hero is below level 10, an enemy mage can defeat them in melee combat, but if they are above 10, then why even cast the spell?! There's no point in it at all...
The only possible advantage of antimagic is in battles with the Chaos army, although there are exceptions here too.
