Pan-Caucasian Empire reforms

[Sarkiss]

No horse archers that I would remember at least not if you don't expand beyond caucasus..
Have'nt been that far. But from the historic descriptions (and EB1) we should have some from the very beginning or am I mistaken here?

Yes, in EB1 that was the concept, iirc, but it was never inplemented: it was easier to get Scythian horse archers, the Armenian ones requiring baracks upgrade. they were also more expensive than the Scythians both in terms of recruitment and the upkeep, iirc.
so you had a paradoxical situation when Hayastan had Scythians as its default horse archers.

you're right though, in EB1 they were considered a regular unit and had no reform-tied restrictions.

The missing units can probably be explained by not having been made yet.
