But I'm used to having a lot of spells. For example, in Heroes 4, there's nature magic. You can summon a lot of creatures, but in the fifth game, there are only elementals and phoenixes:(. That's bad;).

Well, you see, you say "used to." That's already a slightly different category... I don't think it's worth criticizing the game just because it has a slightly different magic system. But all the spells have become much stronger, and their effect is now visible to the naked eye.

But there were abilities in Heroes 4 - a mixed class;) Archmage +20% to all spells, cardinal +5 to resurrection;)

I, for example, played the fourth part very little. But there weren't abilities, just bonuses when choosing certain skills. And here, these are precisely abilities! And they are applied constantly.

But the units could have been made better. Especially the gargoyle;)

The developers are also people and have the right to make mistakes.
