How many factions are there?

I basically agree with you, Drakkosha. It is very important that the balance is not disrupted (and the more factions there are, the harder it is to maintain). You are right that each faction should have its own unique feature. In the current game, I think that's the case. (although someone wrote that the developers ran out of ideas for the Orcs, I absolutely disagree, they may resemble other factions, but only very remotely, on the other hand, they are not very similar to the Orcs from the 3rd Heroes game). I am not against adding a couple more factions, this will positively affect not only the gameplay, but also the plot, IMHO it will be more interesting when there are more participants.
