Reworking the mercenary and factional status...

[Arjos]

i dont recall that epeiros was ever allied with the brettioi in fact i recall that the tarantinioi called in epeiros to help fight against them

Taras called for help against the SPQR, but after few months people from Samnium and neighbouring communities, abandoned Roma to join Pyrros, who promised them local autonomy...
Now I know this happened few years prior to the EB start date, but imo in EBO that isn't such a big deal, especially when we have factions like the KH owning troops from poleis/leagues that were never part of the KH...
But this one is the only point that could go down...

i just plain disagree, i dont think epeiros owned thracian lands

Pyrros was both hailed and later conqueror of the Kingdom of Makedonia, while it's not sure how far south his dominion stretched (Gonatas always regrouped), he most certainly held the north and in Upper Makedonia there were Thraikioi...

i feel that as far as AS goes, all galatians should be mercs, IIRC galatia was a mostly autonomous region, also it was claimed by pontos aswell, also as far as gameplay goes i kind of prefer them that way for some reason

We have examples of Galatikoi siding with usurpers and for example after the treaty of Apamea, they didn't "revolt" against Antiochos Megas for a missing payment (if the Basileus was robbing temples, surely he couldn't pay them), instead the Galatikoi were attacked by Vulso, for the sole reason of having helped Antiochos. In my view all of this points to a symmachia and not to a status of misthophoroi. Some of them were still up for hire, but the tetrarchy (or at least one of the four cantons) always sided with whomever was in power in Anatolia...
Pontos did own the land, because Mithridates invited most of the nobility and assassinated them, but this happened decades after the aforementioned events...

Fact is there were a lot of highland communities and poleis that gained an autonomous status in Anatolia through diplomacy or political choices made by Basileis and the Galatikoi were just one of the many...
Not to mention military settlers and their descendants...

i dont think AS moved into thrace and held those lands long enough

Roman intervention, was mostly due to Antiochos reclaiming the lands of his Progonoi, among these was Thraike, which he secured in 196 BC, refounded Lysimacheia and expanded further north, gaining oaths of allegiance: that gives 6 good years of Seleukid rule...

Kretikoi were well known mercenaries

We know that many Kretikoi went as far as living in Antiocheia and Alexandria, also there are examples of symmachia, like with Doson and there were the so called Neo-Kretikoi, who depending on interpretations, could very well have been Asiatikoi armed and trained in the cretan manner...

Arjos, why are we making a bunch of GREEK units factional for the DACIAN/GETIC faction?

The consensus me and Rob reached so far, was to consider the largest territorial expansion, during the EB time frame, as the base for factional units: Burebista did capture and control all the land from Slovakia to the Black Sea, Kallatis and many other greek colonies were part of that...
