0. There will be 8 units. 3 basic, 3 elite, and 2 alternative champions. Plus, each faction will have 3 units similar to war machines.

1. The level composition is diverse. Different factions have a different number of flying units, archers, infantry, etc.
3. Each faction will have racial abilities, but almost nothing is known about them yet.
4. I think it depends on the presence of dragons. And their presence, apparently, depends on the fans' choice of factions in the voting.

0. I see that, but why 8 if it has always been 7? Maybe we'll have to choose among the champions?
1. I'm talking about heroes; in Heroes 6, a hero of any race can be either a warrior or a caster, while in Heroes 3 and 5, it's different, as far as we remember.
3. I'm talking about something else, like "for example, preparation"; for Necropolis, it's transformation into undead, avenger, artifacts, and the slave market, etc.
4. Well, in Heroes 6, there were birds, I don't remember exactly, but not champions from the factions.
