Well, that's all clear. However, adding "novelty" didn't make the third installment impractical – the Conflux didn't disrupt the balance we were talking about, and even after the release of all the new versions, after "The Restoration of Erathia," for example, "The Shadow of Death," the game didn't lose its ability to surprise. :)
That's what I'm saying: perhaps changing (improving) the heroes on their existing engine, without any Wog, while maintaining balance, is possible.
