You're wrong to think that! Inferno has potential.
I would highlight three key features:
1. "Fast," strong (in my opinion, they are among the top three) and relatively inexpensive ifrits.
2. The best tier 3 unit, which even in the late game, other factions have to take into account due to its high, three-tile, and retaliatory attack.
3. The feature of resurrecting demons.
Depending on the strategy, you can either try to rush with ifrits in the second week or transition into a late-game strategy with demons, archdevils, and the same ifrits. But in any case, I think the focus should be on level 6 units. In this regard, experts who provide +1 speed and many other good bonuses to ifrits unexpectedly become useful.
Also, a good prayer during the construction of a level 4 magic tower helps.
Overall, the city is very complex. It's not for everyone.
