Sylvan versus Fortress.

This time, the demons are gone as well. The dwarves probably won't appear either – and, by the way, they are my favorite race in Heroes 5. It's a real shame. Regarding the elves in Heroes 7, the units are generally decent, but the fairies and dryads don't really add any variety, just like the mermaids/coral priestesses/sea elementals (or whatever they are) in Heroes 6. If the developers have any taste, it's very limited and mediocre. In general, in parts 6 and 7, there's been some kind of chaos in this regard.
