Which units would you like to replace or add?

Dwarves are not needed by mages because mages deal with magic, while dwarves deal with technology.

That's strange logic. If both types of units were engaged in the same activity, then one of the creatures would indeed have no place in the castle. But as it is, one doesn't interfere with the other...

Witch Hunters are not needed because there are already mages.

Witch Hunters and mages are not the same thing. A Witch Hunter is a melee unit with increased damage against magical creatures and monsters. Or, maybe no one is needed in the mage castle at all - aren't there already mages? And Titans. Why do we need anyone else...

What soldiers? Instead, there are golems, and mages are people who like to use magic, not wield a sword.

A golem and a human are two different things. I still can't quite wrap my head around it: there are people in the castle, but they are all mages. What about the division of specializations? A warrior caste, if you give them a good model - oriental armor, a light halberd, a large rectangular shield, would look good. You could say that they are one of the most organized and disciplined infantry in the world, and the formation bonus is that the more warriors there are, the higher the attack and defense (not too big a bonus). Well, I'm just talking about the game. I'm asking again: what are your thoughts? You just keep criticizing...
