Valkrionn
The Hamster King
I've had your mod installed for a while and just now got in a position to use liches. While they feel right in a general sense, I was playing as D'tesh, and they seem like a step down from the Council of Four units. Sure the phylactery guards are massively powerful as a D'tesh player is loaded to the gills with Death mana at that point, but they're immobile. The lich itself, while having great summons of its own needs a Chosen or something to protect it. Maybe you could make your lich get the (RiFE 1.3) D'tesh affinity?
Or, as I don't know what changes you made codewise to make the lich unit a summons, maybe I should be asking Valk to let liches get that promo?
Or maybe Council of Four shouldn't be allowed to become liches, logically speaking? I don't know but this is a neat mod, and it seems to me the civ based on undeath ought to be able to make use of it.
Absolutely all units owned by the D'tesh receive that affinity, so they will be getting it in 1.3.
