Heroes 6 - Discussion

If there are Orcs, then three evil factions will be against the poor, lonely humans... They were always helped to deal with one faction, and now they will have to fight alone against three?? And also against huge hordes of meat (I mean the demons and necromancers - there are always more of them, especially the latter) =((They definitely can't manage without help here. And the balance will be disrupted (( By the way, are skeletons in the neutral creatures or are they not there at all??
