Well, not everyone praises Haven, and I agree that the specialization of Haven is often exaggerated (but it shouldn't be underestimated either, as a lot depends on which hero goes first). I don't understand one thing - many praise Academy, but do mages really have so little mana? To defeat neutrals, you don't need that much. And in a decisive battle, mages always have plenty of mana. After all, one of the problems with mages is that they have too much mana (i.e., knowledge for the sake of mini-arts), which significantly affects other characteristics.
