And there is control over individual Combat Summons. Figure a single-figure unit which has the ability to summon different single-figure, support units based on the situation. For example, an Officer would be a lower-grade hero (with some stack abilities, as a leader), and he would summon standard, musician, healer, ancestral ghost... from his HQ, each with a single support ability. When such units are killed (officer and summons), their side would suffer a pretty large morale loss, however.
I'd second Artfactial about Warbreeds. Modding them would be a good improvement to the game. The Elven one is particularly ugly and offending, lore-wise. In general, I don't like the concept of Warbreed either, and I rather had powerful allies instead in some cases, or the elite of the species in the other cases.
Orc: greater orc like vanilla or above.
Goblin: like the Karagh in AoW2, or like vanilla but larger (same stats as other Warbreeds).
Draconian: like the Infantry (Crusher) in AoW2, that is a dino-like clawed beast.
Human: a battle ogre (vanilla feral ogres are near equivalent to Warbreeds)
Dwarf: a half-giant, same as vanilla I guess, only the text wouldn't describe it as being a monstrosity bred for combat, but a kind of first-born, a rare Dwarf paragon attuned to the Stone.
Elf: a forest spirit
Halfling: vanilla!, only renamed as some kind or kinky ogre.
Frostling: an ice troll (vanilla model could be used).
Also Berserkers visually hurt too, imo: their variety in weapons is small, and they look like basic infantry with same weapons and less armor. I'd rather have Berserkers like agile, semi-naked duelists (they are produced at the Gladiators' Pit, after all). I'd see dual small weapons for Dwarves (see AoW2), dual blade weapons for Elves (a "blade dancer"), a Roman-like Human gladiator. I'd remove tassets and pauldrons too, for some species.
[EDIT]All the above applies to a game modded with Racial Units already. This excellent mod could be better as regard to Warbreeds, imho.[/EDIT]
