Simply knowing the counter-heroes against your opponent is clearly not enough here. Experience, tactics, and many other things matter. Some people find it interesting when all elements are random, but there's still something to learn even in duels.;)

Everything is known by comparison. The highlight of Heroes lies in a certain probability of different randomness, in the various ideas of an opponent, in their tactics. Standard duels lack almost all of this – there’s always the same hero, the same troops, the same spells – you can’t come up with much here. People have even written tactics for different heroes here – how they should act – for example, for Deidre, they provided the order of spells, using which guarantees her victory against some heroes if the player isn’t completely inept. What interest could there be in such a game – only in ATB (Always Turn Based), luck will play a role or not. Everything is known by comparison – normal duels are RTA (10% ATB, 90% skill of the player), standard duels are 90% predetermined (knowledge of counter-tactics for heroes), 5% luck due to ATB, 5% skill of the player. When facing a hero in a duel, I know exactly what he has in store, what his troops are, what his upgrades are; nothing surprises me anymore, so it creates a complete imbalance – some heroes lose to everyone, others are absolute powerhouses. How can this be acceptable?
