What is your opinion about Heroes IV?

...What I meant was that Heroes always had a unique gameplay, as it founded the genre itself, and in the 4th installment, this gameplay was not just changed, but rather stolen.

Based solely on this reason, you should simply hate Heroes 5. I didn't want to discuss the fifth installment in this thread, but I think it's a good example of why this shouldn't be a reason to abandon the game.
