out of all unique characters, only Setnakhte doesn't have his own voice/ conversation......

he is arguably the greatest pharaoh in the game's era, having defeated both Tausret & Irsu.

i like CA Sophia sense of humour, its a shame there isn't special conversation between him & his son Ramesses III,
and how he would interact with the main royal line.

CA also chuck a random god at him.
why Thoth?
looking at the other 4 egyptian minor factions, they take a leftover god who isn't starting deity of the vanilla cast.
Bay already started with Thoth, the only leftover egyptian god is Anubis, not Thoth.
Setnakhte is way more devoted to Set than Seti, even claiming Set as his father.
if you have to repeat starting deity anyway, then give him Set to match the Harris Papyrus.
this randomness kills the lore.

how CA treats Setnakhte is sad.

I believe Setnakhte was intended to be a DLC since he is obviously an important figure and had a unique model and concept art.  However when the launch flopped, a lot of plans changed and I believe Setnakhte was a casualty of this.

If High Tides was Faction Pack 1, and Dynasties was the Map Pack, I think it's very likely Setnakhte was coming in either Faction Pack 2 or 3.
