Well, a debate has started)))
In principle, let's figure out what the advantages of each race are.
For Nature, it's the Portal and Summoning. They are quite acceptable on the map.
For Death, it's Necromancy and the Converter, which are also openly available here.
For Order, it's Charm and Diplomacy. As it turns out, Charm also works, and Diplomacy works very successfully as well.
For Life, its advantage is Resurrection. But how can it be used? If a player has won, it doesn't matter how many units they resurrect – they've already won! And anyway, you can't resurrect more than you've lost. If they've lost, there's nothing to resurrect! The heroes are dead.
Perhaps Resurrection should have been taken into account when creating the map. But how can this be calculated, and is it even possible? That's a question for the mapmaker :) Although... you still can't resurrect more units than were in the army. So, in general, Life doesn't have any racial advantages...
For Chaos, it's Sorcery... As for the Mana Vortex, I don't know, to be honest... I haven't played as Chaos...
For Barbarians, there's a pen that increases unit growth.

But if we can calmly use the advantages of Nature and Death, why can't we use the advantages of Order?:) We ourselves asked to make the race more playable. :) And it turned out to be very playable :)
Only Chaos remains disadvantaged.
It's just that we started considering balance too late. This should have been done earlier. Now, all that's left is to finish the game as it is and then adjust the map regarding balance. And it's not easy to do on this map, due to the specifics of the map itself. That's why we're adjusting it through trial and error :) In practice :) So that next time we have a completely polished map in terms of balance for duels :) And duels, I agree, are quite interesting.
As for Charm... Let's ask STRANNiK about that))) Because it's really unfair to Life when its already small army is being depleted:)
