Regarding the symmetry of the troops: this is planned for later, as there are not so many obvious absurdities (by absurdities, I mean, for example, Hydras being on the 5th tier, and Witches on the 6th). In general, this aspect has long since moved to the background for me.

And in general, complete symmetry is not feasible, for example, in contrast to Angels (7th tier), Faceless Ones (6th tier) should stand. In contrast to Black Dragons, Gold Dragons should stand (adding Dragons to Heaven is not canon). Therefore, symmetry will be present in some places, and we will compensate in others with stat increases. All this, of course, taking into account the lore (freedoms are allowed only in the case of alt-grades of new units, because the developers did not give us any information about the same Faceless Ones, for example, that is, in the case of Faceless Ones, we will get:
- Faceless One / Puppeteer / "..."
Naturally, these freedoms will not contradict the lore.

PS: The mod didn't change its name to "Harmony" for no reason.
