Haven vs. Chaos

While playing on the Equilibrium map, I noticed something: if before (at least on the Whirlwind map), it was possible to create an illusion of a Black Dragon, in this mod, they decided to remove that possibility.

Well, essentially... that's actually correct. If you're going to protect Black Dragons from magic and all sorts of magical effects, then you need to go all the way. Therefore, banning illusions is a logical continuation of this approach.

This significantly reduces the chances of Order against Chaos; in fact, only Titans can realistically counter Black Dragons, which means you'll have to give up on mages and maybe even genies, which will significantly complicate clearing neutral creatures.

I don't think the chances will decrease. Perhaps the tactics will change, but that's up to the player. Genies are more versatile than just illusionists. When you have enough of them, a simple bolt can even be more effective than various illusions.

In general, it seems that the mod didn't eliminate the imbalance; it simply wanted to make players think more when choosing their units. So that it wouldn't be just 100% genies, vampires, cyclops, etc.
