Balance in HotA.

Which game are you talking about? The gameplay in Heroes is already unrecognizable compared to SoD (in its own way).

Well, it's a shame if you think so.
The abilities of Magogs, Liches, Phoenixes, Archdevils, the order and cost of building cities, the cost and growth rates of creatures, negative luck, bug fixes that significantly change the gameplay – all of this is already "very different from SoD." Nothing like SoD with Armageddon's Blade or Armageddon's Blade with Horn of the Abyss was done.

Why is it okay to change all of the above (since it all drastically changes the familiar gameplay), but not the SoD spells?
