In your opinion, which faction is the strongest in Heroes 5? Let's discuss the advantages and disadvantages of each faction.

I love playing as the Sylvan faction, but I don't think they're the strongest; to be honest, I never have. (They are a decent, atmospheric, and enjoyable race, but not the strongest, as there's always a bigger fish). I've repeatedly seen that they can be easily defeated with the right skills. I used to think the Academy was the strongest because of their magic, archers, and strong infantry, but... now I disagree with my previous opinion because I've again seen that mages can be easily defeated if necessary. I've also dismissed opinions about the strength of other factions. Anyone can be defeated by anyone else – balance exists, folks! ;) :D So, all races are equally good and strong, IMHO. And if someone thinks that someone is stronger, I think they should try playing with the "weaker" ones.
