MMH5.5 - Heroes of Might and Magic 5.5

I think that Inferno is too strong a faction because of the Hellhound, which has a very long movement range and deals damage to multiple units at once, and the Nightmares, which can reach the enemy in one turn. Also, there's the ability to open portals. However, the runes for the Fortress have become much weaker, and they are almost useless. Perhaps they should have been weakened, but not to this extent.
