There was only one expansion pack for "Heroes 4". It's hard to believe it was unpopular :p.
The more factions, the better. Variety. In "Heroes 5", they easily created six excellent campaigns with an interesting plot for each faction. What's wrong with "Heroes 6"? And if the developers don't bring back at least seven factions from "Heroes 5", the fans will tear them apart :):p!
No one is saying that 6 is worse than 5. It's better to have all 8 :), but let's not have gnomes if they're going to be like in Heroes 5)))
