Could you please elaborate on why a Warlock hero is incompatible with Lizardmen? They both live in the Dungeon. There are hydras, dragons, and other reptiles there. Who should the hero ride then? A hydra? That would look ridiculous. Maybe a minotaur? No comment... But Lizardmen are the most optimal option. And there is such a unit. Only regular warriors ride regular lizards, while heroes ride major ones.
Regarding mages, do they live in the sky? I'm hearing this for the first time. They actually live on the ground. It's just that their cities are designed in a strange way, but that's a minor detail. Maybe they have a portal there.
Heh) I think he doesn't mean the 5th game, but the entire fantasy world)) and how it is presented in the 5th game.
If so, then I agree)) Where have you ever seen Dark Elves riding dinosaurs? And who came up with the idea of putting Hydras underground? I don't remember that in the myths (about hydras).... Creativity is needed, new ideas, etc.) but not such nonsense))) IMHO
P.S. This applies to some other aspects of the game as well.
