Part of Greek V13 seems Arvanite, but more of known V13 lineages seem native to Greece. I do not understand why do some Albanians constantly need to patronize V13 and make up a ludicrous idea that "V13 is Albanian", as Illyrian languages were not brought or even mostly spread by V13.
Some Greek clades show Late Bronze Age or Early Iron Age arrival to Greece, but the notion of these being "Illyrian" is beyond ridiculous. Dorians most definitely were not Illyrian.
E-V13 originates from Western Balkan, Cetina culture who
were practically enemies (one of important Cetina places became overrun by J-L283 elements as original Cetina culture waned and these had almost no contact despite being neighbors for some time) of incoming proto-Illyrians. And they migrated to Central Balkans and further East where they became part of Danubian archaeological complex which comprised the bulk of Iron Age Daco-Thracian culture, yet Cetina people spoke an Indoeuropean language of some sort, if Thracian is older language cultures like Vatina which must be associated with V13 also spoke Thracian.
E-V13 bastion in the West were likely people like Liburni who were not Illyrians proper, and always had considered themselves as separate.
Regarding your ludicrous comments about V13 being spread to Bulgaria in Middle Ages, mirrored by some of you, V13 in those areas is already very diverse, most importantly CTS1273 is more basally diverse than Albanian with
less Bulgarians deep tested which speaks volumes.
Yet there is archaeological and genetic diversity point in Southern Albania where some clades concentrated themselves in LBA/EIA likely pushed from the North by various Bronze Age collapse waves.
In short in Neolithic V13 were in Illyrian areas, in PIE time they embraced violence (don't forget that E1b1b languages are spoken by the entire Middle East and not J, T, L languages though Semetic branch was spread by P58 mostly) and made their base to the East.
One Central Balkan E-V13 group was likely one of (proto) Illyrian groups, these had migrations to modern South Albania, so I guess they comprised various tribes.
I already spoke of some clades such as E-L241 and E-Y3183. Some evidence points to these being potentially related to Dorians. These clades might have spoken Dorian Greek originally, they are both under E-Z16659.
You are that Kastrioti dude right?? You register on so many places under so many nicknames, but one thing always remains the same, always talking about some Ottoman leftovers among Albanians, Jevgs etc., I saw one of your older posts here few years ago talking about E3b arriving with Ottomans.
