Harmony - Troop Symmetry

I'm not just going to swap out the Inferno units from the fifth game with the Inferno units from the sixth; what's the point of that? First and foremost, I'll make sure that the demons have both a low-level ranged unit and an elite ranged caster. I'll probably add the Ifrit (I originally planned to replace the Nightmare with it), but I'm leaning towards this:
1 Imps
2 Cerberi
3 Succubi
4 Incubus
5 Nightmares
6 Ifrits
7 Pit Lords
At the same time, the Djinns of the Academy will be moved to tier 6, and the Rakshasa will be moved down to tier 5.

In any case, I'll finish the mechanics first (in principle, all that's left is to complete the skill wheel and review the heroes, of which there are currently 16 per faction – the number should be a multiple of the maximum number of players, in case all 8 players on one map belong to the same faction, the number of native heroes they have should be the same).
