Well, I've been playing since '99 with different factions, including Inferno. I can easily win on impossible difficulty, but that's because the AI doesn't really think and doesn't use the strengths of its faction or understand the weaknesses of mine. But playing Inferno against a human player is practically suicide (unless the Inferno player is significantly better than their opponent). By the way, I still haven't found anyone who really loves this faction and plays it the most. I think that's telling.
