Heroes 5.5 WarGame Edition - Tactical Edition.

According to the lore, ogres are man-eating giants, which perfectly fits the image of executioners. Wikipedia states their height ranges from 2 to 4 meters. Here, it's 3 meters. Regarding intelligence, they match the portrait of a typical Ashan orc (while smaller orcs might be smarter, as in Warcraft). The use of bladed weapons is unusual here, but we don't necessarily have to follow all stereotypes immediately. And certainly, Ashan cyclops adhere to them even less.
Cannibalism can be explained by the fact that ogres are pure predators, unable to feed on plant-based food. For them, war is hunting. So why would they disdain the meat of weaker creatures, military trophies?
I quote from Wikipedia:

They make trophies and talismans from the bones of their victims, with which they decorate both their dwellings and themselves.

+ pay attention to the visuals of both ogre tiers.
In general, the word "ogre" is not planned to be used in the name, only in the description, so opponents of introducing ogres shouldn't be too worried about it.

Actually, I'm even glad that this version with ogres allowed us to explain the giant leaders. Because I was always bothered by the fact that some orc could surpass a minotaur in size. Here, orcs are 2 meters tall, minotaurs are 2.5 meters tall, ogres are 3 meters tall, and the hierarchy of giants is maintained.

As for trolls, they resemble cyclopes more, or rather a hybrid of a troll and a cyclops (one-eyed trolls). There were very similar trolls in The Lord of the Rings (but smaller). In the description, you can mention that some races call them trolls.

In the post, I updated information about the weight of knights: instead of 1000 kg, now the weight is 800-1000 kg.
The visual corresponds to a weight of 800 kg.

Weight categories of heavy cavalry:
1) cuirassiers 700-800 kg (budget heavy cavalry, not represented in Heroes 5), would be approximately twice as weak as knights, somewhere on the level of centaurs
2) knights, paladins 800-900 kg
3) champions 900-1000 kg (the most powerful but less maneuverable horses are used, more suitable for tournaments than for war)
