Comrade Horn – and everyone who helped make the decision – are you sure that you chose the best option for reassigning the magic schools?
Let me explain. The thing is that Air and Earth magic are more versatile (according to the developers' intention) than Fire and Water. This is because there are 18 hero classes, and Earth and Air can be learned by all of them, albeit with varying probabilities. However, some hero classes have a zero percent chance of learning Fire and Water... if I remember correctly, the "Ranger" and "Beast Master" classes will never learn the Fire school naturally, and the "Barbarian" and "Lord" classes will never learn the Water school... This means that 25% of the heroes are simply deprived of key spells as a result of the changes. What's even more unfortunate is that in the Elven castle, "Town Portal" was often given, but now, even if it does appear, all the Elven monsters (Kir, Mephala, Thorgrim, etc.) will simply be rendered useless.
The same applies to other monsters: Tazar, Korvak, Bron, Gervulf, Gunnar, Shakti, Damacon, Arlargh, Kraghak, Gurnisson. :(
