- Tactics skill in Heroes 3.

I've hated the Tactics skill since the first day I started playing, because instead of building, you can take another great skill. When I get this skill, I immediately load Avtosave. Do you like it? Who has it as their favorite skill?

Hmm, and what don't you like about this skill? It's a great skill that allows you to arrange your troops as you like before the battle. It's great when you have it, and it's very bad when you run into an enemy hero with expert Tactics.
If it appears, I always try to take it, even if it's at the expense of something else.
Against neutrals: it allows you to minimize losses or even reduce them to 0, especially if the game is focused on ranged units. It's also a very useful thing in the early stages of the game.
Arrange the stacks so that it's convenient, for example, if you have expert Tactics and mass Haste/Prayer on everyone, and the first turn is yours, then you can do a lot when all your units reach the enemy in one turn and inflict significant damage.
It's hard to call it a favorite skill, but still, when this skill appears, I almost always take it (except when the game on the map is coming to an end and it's better to max out something you already have before the last few battles, or a more useful thing appears, such as Ballistics, if you need to storm a castle with strong defenses; or an expert skill in some magic, to increase damage, well, in general, it depends on the circumstances).
And I advise you to reconsider your attitude towards this skill.

Here's a great example from Marmot, where the Tactics skill played its role in the victory.
I think there are plenty of examples where Tactics, in combination with something else, decided the battle.

Not knowing the tournament rules is not a bad thing. Maybe the person is playing for the first time. What matters most is not how you play the first time, but how you play after a few months. Everyone can express their opinions on forums, even if they are wrong from the point of view of the majority. And you need to treat this calmly. In the same offline game, Tactics is taken much less often.

Even when playing scenarios and campaigns, or just playing offline on a random map or something else (offline tournament), it allows you to break through some guards earlier, develop faster, gather troops, and come to defeat the computer enemy.
Once, when playing a hot-seat game with a friend on a random map, I was shown a great example where Tactics played a very important role.
What can be more valuable than Tactics? What do you think is more useful?
After all, there are only 8 skills, and you can definitely find a place for the Tactics skill.
Of course, often when playing on a random map or scenario, Tactics doesn't appear, and the game goes without it, or it appears right before the very end, when it's more important to improve an existing skill.
I myself have played with heroes who have the Tactics skill, or subsequently acquired it, and it really makes the game more comfortable and convenient.
But in the end, all I can say is that everyone is different.
